Contract-Grade Shower Doors Manufacturer: Project Sourcing for Multifamily & Commercial Builds

What "Contract-Grade" Means for Shower Doors (and Why It Differs From Residential)

When a developer specs a 220-key select-service hotel or a 180-unit garden-apartment community, the shower enclosure stops being a single bathroom purchase and becomes a repeatable unit cost multiplied by hundreds of installs. That changes everything. A residential door is bought once, installed by a local glazier, and judged on looks. A contract-grade door has to survive thousands of slide cycles a year, resist corrosion in a humid coastal property, ship by the container without a breakage problem, pass a building inspector on safety glazing, and arrive with documentation a general contractor can drop straight into a submittal binder.

Most of the suppliers ranking for the term contract grade shower doors manufacturer are distributors or regional glass fabricators reselling someone else's hardware. They cannot give you the true landed cost, the MOQ, or the test reports because they are not the factory. SANIKB is the factory. We supply sliding, framed, semi-frameless and bathtub shower doors through one-stop sourcing for project buyers, and we sell direct, quote-based, with no distributor markup layer. The owner runs real hotel and engineering contract projects, so this guide is written from the procurement side of the table: what to actually source, the specs that pass inspection, realistic MOQ and lead times, and the submittal workflow architects and GCs require. Browse the full range of contract-grade shower doors as you read.

Commercial Shower Door & Enclosure Configurations We Supply

Different property types and bathroom footprints call for different door mechanics. We manufacture across the configurations a project specifier actually mixes within a single building, and we will be honest about what each model is rather than over-claiming a premium category for a value product.

Sliding / bypass doors

The workhorse of high-turnover commercial bathrooms. Two panels bypass on a track, so the door needs no swing clearance, which matters in compact hotel and apartment baths. Our SN-R21 fluted-glass sliding shower door pairs a reeded/fluted tempered glass panel with a slim header track for a more upscale guest-bath look without leaving the durable sliding category. For wider openings, the P-11 aluminum-framed double sliding shower door uses a fully framed aluminum perimeter for structural rigidity and a lower price point that scales well across hundreds of value-tier units.

Framed sliding enclosures

When the project needs a complete corner or alcove enclosure rather than a single door, the Y-Series framed sliding shower enclosure delivers a framed-glass enclosure engineered to sit on a matching base. Framed construction is the right call for limited-service hotels, student housing and multifamily where ruggedness and replaceable hardware beat a frameless aesthetic.

Bathtub doors

Many hotel and apartment baths are tub-shower combos. The S-8 sliding bathtub door is a framed sliding door sized to standard tub decks, replacing a curtain with a wipeable tempered-glass panel that cuts housekeeping time and reduces mold complaints over a property's life.

We also produce semi-frameless and frameless configurations on a quote basis for luxury and full-service properties. To be clear about the models above: the SN-R21 is a fluted sliding door, the P-11 is an aluminum-framed double sliding door, the Y-Series is a framed enclosure, and the S-8 is a framed bathtub door. We do not market any of those four as frameless.

Real Model Comparison (Built From Our Actual Catalog)

Use this as a starting matrix when you scope a fixture package. Exact dimensions, glass thickness and hardware finish are confirmed per model and market in your quote, so this table reflects configuration and intended application rather than fixed sizes.

Glass Engineering & Specifications

The single biggest spec gap on competing pages is that nobody puts the full glass-engineering block in one place. Here is what to specify and confirm per model:

• Thickness: tempered glass is offered in commercial thicknesses (commonly 6mm/8mm; 10mm and 12mm available for frameless and heavy-use builds). Heavier glass costs more and weighs more per container, so match thickness to property tier rather than over-specifying every unit. Final thickness is confirmed per model and market.
• Edgework: exposed edges are ground and polished (flat-polished or pencil-edge) so they are safe to handle during install and clean over the property's life.
• Coatings: an easy-clean hydrophobic coating is available to reduce hard-water spotting and cut housekeeping labor; protective interleaving is used in packing to prevent surface scuff in transit.
• Glass pattern/finish: clear, frosted and fluted/reeded (as on the SN-R21). Pattern is a specification choice, not a structural one.
• Hardware finishes: chrome, brushed nickel and matte black are standard; finishes for humid and coastal properties should be confirmed for corrosion resistance per the destination market.

Safety Glass Standards & Code Compliance

For US commercial projects, shower and bath enclosure glazing is hazardous-location glazing and must be tempered safety glass. The governing references your inspector and architect will look for are CPSC 16 CFR 1201 (Category II for shower/bath enclosures) and ANSI Z97.1 safety glazing. All SANIKB shower glass is fully tempered safety glass intended to meet these requirements, with conformance confirmed per model and destination market, and we provide the corresponding test documentation with the order. For occupancy and assembly requirements, your design team will also reference the applicable building code edition adopted by the jurisdiction.

Anti-shatter & safety film for high-traffic properties

For fitness/locker-room and high-traffic public applications where an additional anti-shatter margin is wanted, a safety/anti-shatter film can be specified as an option. We will quote it explicitly rather than bundling it silently, since it adds cost most limited-service guest baths do not need.

ADA & Barrier-Free Compliance

Accessible units are where generic shower-door suppliers go quiet, and where a procurement team gets burned at inspection. For ADA roll-in and transfer-shower configurations, the door or opening must preserve the required clear width and must not obstruct the transfer seat or the turning/clear-floor space. The authoritative reference is the 2010 ADA Standards for Accessible Design. In practice that means pairing accessible units with a curbless/low-threshold base and coordinating the enclosure so it does not conflict with grab bars or the seat. We manufacture to roll-in and transfer-shower configurations and coordinate the door with a matching curbless pan, which is straightforward when you source the door and base from one factory. Pair your door spec with our shower base options and complete tub-shower packages from the shower and bath collection so the enclosure and pan are dimensioned to each other from the start.

Hardware Built for Commercial Cycles

The failure point in any commercial shower door is the hardware, not the glass. Rollers, hinges and guides take the abuse. For contract use we specify cycle-rated rollers and guides, PVD/corrosion-resistant finishes for humid and coastal properties, and we keep replacement parts available so a property manager can swap a worn roller years later instead of replacing the whole enclosure. When you standardize on a model like the P-11 across a portfolio, that replacement-part continuity is worth more than a few dollars of upfront savings on a one-off door.

By Property Type

Matching configuration to property type is where an experienced manufacturer earns its keep:

• Limited-service hotels & multifamily: framed sliding (P-11) and bathtub doors (S-8) for ruggedness, low cost per unit and easy part replacement.
• Boutique / mid-to-luxury hotels: fluted sliding (SN-R21) or semi-frameless for a guest-bath upgrade without sacrificing durability.
• Student housing & dormitories: framed enclosures (Y-Series) and tub doors built for heavy, careless use and bulk replacement parts.
• Senior living & healthcare: ADA roll-in/transfer configurations paired with curbless bases and grab-bar coordination.
• Fitness / locker rooms: framed enclosures with optional anti-shatter film for public high-traffic safety.

Factory-Direct Pricing & MOQ

Because we are the manufacturer, your price is the factory price plus freight and duty, not a price that has already passed through a distributor and a local fabricator. MOQ is set per model, but the practical economic unit for a project is a container load, and a 100-300 key hotel or a mid-size apartment community clears MOQ in a single PO. Volume tiers apply as unit counts rise. Samples are available before you commit, and sample cost is credited against a production order so evaluating the real glass and hardware costs you nothing once you proceed. The honest landed-cost math, which a distributor cannot show you, is the core reason project buyers source direct.

Lead Times & Production Capacity for Multi-Unit Projects

Lead times are confirmed per order, but as a working guide: standard catalog configurations in a single container typically run on a multi-week production window from approved sample and PO; custom sizes, private-label branding and special finishes add to that; sample lead time is shorter and runs in parallel while you finalize the spec. We schedule production against your construction timeline and can stage shipments by building phase so doors are not sitting on a job site for months before installation. For large portfolios we plan capacity ahead so repeat POs for the same fixture package keep flowing without re-tooling delays.

Submittals Made Easy

Architects, GCs and procurement teams cannot approve what they cannot document. We support the submittal package a project actually requires: model cut sheets with confirmed dimensions and glass spec, finish samples, and the safety-glazing test documentation (CPSC/ANSI) that an inspector wants on file. Provide your base/alcove dimensions and we confirm fit before production; for custom runs we work from your field-measure or shop-drawing dimensions so the door arrives sized to the opening. Standardizing the package across a portfolio means the second and third properties reuse the first submittal almost wholesale.

Logistics for Large Orders

Glass survives ocean freight only if it is packed for it. We crate glass in heavy-duty wooden crates or reinforced cartons with foam and corner protection, interleaved to prevent surface scuff, and palletized for container loading and bracing against transit shock. We optimize the load plan to maximize doors per 20ft or 40ft container and lower per-unit freight, and each shipment ships with a packing list mapped to your PO. Breakage-replacement handling is agreed in the contract up front, so any transit damage is resolved by replacement rather than a dispute, and customs/landed-cost figures are made clear in the quote so there are no surprises on arrival.

Warranty, Quality Control & Compliance Documentation

Every order goes through in-house QC before crating: glass tempering and edgework inspection, hardware function and alignment checks, and finish inspection. We supply the compliance documentation (safety-glazing test reports, certificates of conformance per model and market) with the shipment. Warranty terms are confirmed per order and per model so a property owner knows exactly what is covered over the building's life.

Project Workflow: From Spec & Sample to Delivery

The path from inquiry to installed door is deliberately simple: (1) you send your unit count, base/alcove sizes, configuration and finish; (2) we return a quote with MOQ, volume tier, lead time and landed cost; (3) we ship samples (cost credited to the order) for sign-off; (4) you issue the PO and approve the submittal package; (5) we produce, run QC, and crate; (6) we ship by container with documentation and an agreed breakage-replacement clause; (7) we support replacement parts over the property's life. Because the door, base and the rest of the fixture package can come from one factory, you get single-vendor accountability across the whole bathroom.

Why Source From the Manufacturer

SANIKB is a one-stop kitchen and bath fixture factory: shower doors, bases, sinks and faucets under one roof. That means a developer can spec a complete, dimensionally-coordinated bathroom package from a single accountable source rather than chasing four vendors. For the deeper sourcing playbook, see our guide to a contract-grade bathroom fixtures supplier and our breakdown of working with a hotel bathroom fixtures supplier on a full property package. When you are ready to scope your enclosures, the complete range of contract-grade shower doors for hotels and multifamily is the place to start.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for contract-grade shower doors?

MOQ is set per model and configuration, but for project orders we typically work from one 20ft or 40ft container as the practical economic unit. Standard sizes carry lower minimums than fully custom dimensions or private-label hardware. A 100-300 key hotel or a multifamily community almost always exceeds MOQ in a single PO. Send your unit count, base sizes and finish, and we confirm the exact MOQ, volume tier and landed cost per door in the quote.

How long are lead times for a multi-unit hotel or apartment project?

Lead times are confirmed per model and order size, but as a working guide: standard catalog configurations in a single container run roughly 30-45 days from approved sample and PO; custom sizes, private-label branding or special finishes add to that; sample lead time is shorter and runs in parallel while you finalize the spec. We schedule production against your construction timeline and can stage shipments by phase so doors are not sitting on site months before installation.

Do your shower doors meet US safety glazing codes?

Yes. All glass is fully tempered safety glass intended to meet the relevant safety glazing requirements for shower and bath enclosures, with conformance confirmed per model and destination market. For US projects the governing references are CPSC 16 CFR 1201 (Category II) and ANSI Z97.1. We supply the corresponding test documentation with the order so your GC can drop it straight into the submittal binder for inspector sign-off.

Can you do OEM/ODM and private-label for our brand?

Yes. We are a factory-direct manufacturer, so OEM/ODM is core to what we do: custom sizing to your bases, your choice of glass pattern and hardware finish, branded handles or hardware, and private-label packaging and documentation. Whether you are a distributor building a house line or a developer standardizing a fixture package across properties, we manufacture to your spec rather than reselling a fixed catalog.

How do you package and ship shower doors to prevent breakage over ocean freight?

Glass is shipped in heavy-duty wooden crates or reinforced cartons with foam and corner protection, palletized for container loading and braced against transit shock. We optimize the load plan to maximize doors per container and reduce per-unit freight. Each shipment is documented with a packing list mapped to your PO. We confirm breakage-replacement handling in the contract up front so any transit damage is resolved by replacement rather than a dispute.
