Importing shower enclosures means reading spec sheets, quotes, and factory emails full of terms like SGCC, PVD, DFM, and bypass. If you are new to the category, the vocabulary alone is enough to make you hesitate before challenging a quote or spotting a weak supplier.
This glossary defines 30 shower enclosure terms every B2B importer and junior procurement agent should know, grouped into five practical categories. Each entry explains what the term means and why it matters when you are specifying, pricing, or inspecting an order, so you can hold a conversation with a factory on equal footing.
Key Takeaways
- El 30 terms fall into five groups: glass and safety, door configuration, space-saving shapes, hardware and finish, and commercial terms.
- Safety terms (SGCC, ANSI Z97.1, heat soak test) decide whether a project passes inspection. Get the paperwork before you ship.
- Door-type terms (sin marco, derivación, pivote, entrada sin cita previa) map directly to bathroom size and budget.
- Hardware terms (PVD coating, salt spray test, cycle test) decide how long the enclosure survives daily commercial use.
- Commercial terms (Cantidad mínima de pedido, OEM/ODM, DFM, plazo de entrega) shape your cost, timing, and risk as an importer.
- Knowing this vocabulary lets you read a spec sheet, question a quote, and compare two suppliers on the same basis.
Glass and Safety Terms
Glass is the largest cost component in a shower enclosure and the part that carries the safety liability. These six terms come up in almost every specification and every customs document.
1. Vidrio templado
Glass heated to roughly 620°C and then cooled rapidly, which puts the outer surfaces into compression. It is four to five times stronger than annealed glass and, when it breaks, crumbles into small blunt cubes instead of long shards. Every commercial shower enclosure uses it. A serious factory tempers its own panels and verifies each batch rather than buying pre-cut glass from an unverified source.
2. Vidrio laminado
Two sheets of glass bonded with a PVB interlayer. If the panel breaks, the interlayer holds the fragments in place instead of letting them fall. Specifiers call for laminated glass in overhead glazing, high-traffic public areas, and any location where a dropping panel could injure someone. You can read a fuller comparison in our guide to tempered vs laminated glass for shower doors.
3. Heat Soak Test (HST)
A controlled oven cycle run after tempering. It forces panels that contain nickel-sulfide inclusions to break inside the factory instead of months later on a finished hotel wall. Ask for HST on large frameless panels. It is inexpensive insurance against a rare failure that is very expensive to fix after installation.
4. SGCC Certification
The Safety Glazing Certification Council (SGCC) mark is a widely recognized certification for safety glazing products in the North American market. For hotel and multi-family residential projects in the US and Canada, safety glazing that meets applicable standards is often required, and SGCC certification can help demonstrate compliance. Copies of the relevant certificates should be included with the project documentation and shipment records to support product verification, site inspection, and regulatory compliance.
5. ANSI Z97.1
The US performance standard for safety glazing used in doors, bañeras, and shower enclosures. It defines the impact test a panel must pass. SGCC listing is built on this standard, which is why the two names appear together on most spec sheets and quality reports.
6. Low-Iron (Ultra-Clear) Vaso
Standard tempered glass carries a faint green tint you can see along the edges. Low-iron glass removes most of that iron content for higher clarity and truer color. It costs about 20-30% more and shows up in luxury hotel bathrooms that are marketed as a design feature rather than a utility.
Door Configuration Terms
These six terms describe how an enclosure opens and how much space it needs. Door type is usually the first decision a specifier makes, because it is constrained by bathroom dimensions, presupuesto, and accessibility requirements.
7. Sin marco
An enclosure held by minimal clips and hinges with no metal surrounding the glass edges. It needs thicker glass, 10mm as a minimum and 12mm for wide panels, because the panel itself provides the rigidity. The clean sightline makes a bathroom feel larger, which is why luxury hotel brands specify it in premium room categories.
8. Sin framas
A hybrid that frames only one or two edges, usually the top rail or a single vertical side, and leaves the remaining edges exposed. You get most of the frameless appearance with more structural rigidity and easier installation, and the partial frame absorbs minor wall irregularities across a building where no two bathrooms are perfectly identical.
9. Enmarcado
Every glass edge sits inside an aluminum or stainless steel channel. Framed units offer the strongest water containment, hide out-of-plumb walls completely, and cost the least. Mid-scale hotels and gym locker rooms favor them because a single cracked panel is cheap and quick to replace without touching the rest of the unit.
10. Derivación (Corredizo) Puerta
Two or three panels that glide past each other on a top or bottom track. Because nothing swings outward, bypass doors save floor space and suit compact hotel bathrooms and accessible layouts. Roller quality decides how long they stay smooth, so this is where the hardware terms below matter most. Browse the full puerta corredera de ducha range for configuration options.
11. Pivot Door
A single panel that rotates on a top-and-bottom axis rather than on side hinges. It gives a wide entry opening and a modern statement, but the swing arc needs clear floor space. Pivot doors suit medium and large bathrooms and are a poor fit where the arc would hit a vanity or toilet.
12. Walk-In / Fixed Panel
One or two fixed glass panels with no door at all. Water flows past the open edge into a linear drain. This is the standard configuration for wet rooms and accessible roll-in showers, and its simplicity means fewer moving parts to fail over a decade of daily use.
Space-Saving and Modular Terms
Compact bathrooms and fast-track construction projects drive these six terms. They describe corner shapes that reclaim floor space and factory-built units that shorten installation time on site.
13. Neo-Angle
A five-sided corner enclosure with two angled door panels that meet at a corner. It fits a square bathroom corner while giving a wider entry than a standard corner unit, which makes it a common choice for small hotel rooms and apartments.
14. Quadrant
A corner enclosure with a curved front that follows a quarter-circle footprint. The curve saves space and softens the appearance of the room. You will see quadrant units specified where a hard square corner would crowd the floor area.
15. Diamond
A corner unit whose front panels form a diamond shape. It maximizes interior standing room inside a tight corner and is one of the space-saving shapes KJ Bath produces for small apartment and hotel bathrooms.
16. Plegado
A door built from two hinged panels that fold together as the door opens. It needs the least clearance of any swinging door, which makes it useful where a pivot or hinged door would collide with a nearby fixture.
17. Modular Shower Pod
A factory-assembled, self-contained shower unit delivered as one piece or in large modules. It drops into place on site and cuts installation time sharply, which is why long-stay apartment, alojamiento para estudiantes, and healthcare projects specify it. See the modular shower pod options for prefab deployments.
18. cuarto húmedo
A fully waterproofed bathroom where the shower sits at floor level with no curb or tray, relying on floor slope and a linear drain to manage water. Wet rooms pair with fixed walk-in panels and depend on careful detailing to keep water inside the shower zone.
Hardware and Finish Terms
The glass gets the attention, but the hardware does the work and usually fails first. These six terms decide how long an enclosure stays smooth, sealed, and good-looking under daily commercial use and constant cleaning.
19. PVD Coating
Deposición física de vapor, a vacuum process that bonds a hard, corrosion-resistant finish onto hardware. It holds color and shine far longer than standard electroplating in humid, chemically cleaned bathrooms, and it is what keeps matte black and brushed gold finishes from fading or pitting.
20. Prueba del spray de sal
A corrosion test where hardware sits in a salt-fog chamber for a set number of hours. Commercial-grade fittings should survive at least 48 hours with no visible rust. If a supplier cannot hand you a salt spray report, treat their corrosion claims as unproven.
21. Rodillo de acero inoxidable
The wheel that carries a sliding door along its track. Grade 304 stainless resists the constant moisture and cleaning chemicals of a hotel bathroom. Roller grade and bearing quality separate a door that stays smooth for years from one that develops play after a few thousand cycles.
22. Cycle Test
A rig that opens and closes a door tens of thousands of times to simulate years of use. KJ Bath rates its rollers to 100,000 ciclos de empujar y tirar, a figure that maps to roughly a decade of daily hotel use before the moving hardware needs attention.
23. Magnetic Seal
A weather-stripping system where two magnetic strips on adjoining panels pull themselves together to close the gap and keep water inside the enclosure. It is a small, cheap part that decides whether a frameless door leaks onto the bathroom floor.
24. Wall Channel (Profile)
The U-shaped aluminum or stainless strip fixed to the wall that receives a glass panel. It anchors the enclosure, allows a little adjustment during installation, and carries the finish that ties the whole unit together visually.
Commercial and Quality Terms
These six terms shape the business side of an order: how much you must buy, who owns the design, how the factory de-risks your drawings, and how long everything takes. They are where most first-time importers get caught out.
25. Cantidad mínima de pedido (Minimum Order Quantity)
The smallest number of units a factory will produce for an order. KJ Bath sets its MOQ at 10 sets for its main models, which is low enough for an importer to test a market without committing to a full container of stock.
26. OEM / ODM
OEM means the factory builds to your design and your brand. ODM means you license and brand a design the factory already developed. Importers use OEM for a differentiated product and ODM to launch quickly without their own engineering team.
27. DFM (Diseño para fabricación)
A review where the factory checks your drawings for anything that is hard, costly, or risky to build and suggests changes before tooling starts. Good DFM catches problems on paper instead of on the production line, where they are expensive to fix.
28. Value Engineering
The practice of adjusting a design to cut cost or installation risk without giving up performance. On hotel projects, a manufacturer with in-house engineering can propose changes that save money across hundreds of identical bathrooms at once.
29. Plazo de entrega
The working days between order confirmation and goods ready to ship. KJ Bath quotes about 15 working days for samples and 30 days for a first production run, shortening to 20-25 days on repeat orders once molds and material schedules are set.
30. Drop Test / ISTA
A packaging test where a boxed unit is dropped from set heights to simulate parcel handling. Passing an ISTA-style drop protocol is how a supplier proves glass will survive courier and last-mile delivery, which directly protects an e-commerce seller’s damage and return rate.

How to Use This Glossary When You Source
A glossary is only useful if it changes how you buy. Keep this shower enclosure terminology close when you read a quote or a spec sheet, and use it to ask sharper questions.
- Match the door configuration to the bathroom size first, then work down to glass thickness and hardware grade.
- Require SGCC, CE, and ANSI Z97.1 documentation in the contract, not as a promise after payment.
- Ask for salt spray and cycle test reports on hardware before you commit to a finish.
- Confirm MOQ, plazo de entrega, and packaging drop-test results in writing so your landed cost and schedule are real.
- Order a sample. A 15-day sample lead time is standard and lets you verify glass clarity, acabado de hardware, and seal quality.

Preguntas frecuentes
What does SGCC mean on a shower enclosure spec sheet?
SGCC stands for the Safety Glazing Certification Council, the recognized safety-glass listing for the North American market. It confirms the glass was tested to ANSI Z97.1 for impact resistance. Hotel and multi-family projects in the US and Canada usually require SGCC-certified glass with certificate copies that follow the shipment.
How thick should shower enclosure glass be?
Commercial enclosures use tempered glass from 6mm to 12mm. Frameless designs need 10mm as a minimum and 12mm for panels wider than about 1000mm. Framed units can use 8mm because the metal channel adds structural support.
What is a normal MOQ when importing shower enclosures?
Minimum order quantities vary by factory. KJ Bath sets its MOQ at 10 sets for its main models, which is low enough for a first-time importer to test a market without committing to a full container of inventory.
What is the difference between OEM and ODM?
OEM means the factory manufactures to your design and your brand. ODM means you license and brand a design the factory already developed. Importers choose OEM for a differentiated product and ODM to launch faster without their own engineering resources.
How long does production of a custom shower enclosure order take?
KJ Bath quotes about 15 working days for samples and 30 days for a first production run. Repeat orders usually shorten to 20-25 days once molds and material schedules are already in place.
