Standard hotel shower pans come in three common sizes: 32x60 inches, 36x60 inches, and 48x60 inches. The 32x60 is the most common — it fits the same footprint as a standard tub and works in most hotel bathrooms without structural changes. The 36x60 offers more elbow room and is becoming the new baseline for mid-scale and upscale brands. The 48x60 is the ADA standard, designed for roll-in wheelchair access.
Renovation pans are built to match standard tub footprints with the drain in the original location. Custom sizes exist for older buildings or unusual layouts, but they cost more and take longer.
If you're specifying pans for 50+ rooms, stick with standard sizes. It keeps costs predictable and lead times short.
This is the size most hotel bathrooms are built around. It matches the footprint of a standard 60-inch tub, which means you can pull out the tub and drop in a shower pan without reframing the space.
A 32x60 pan gives you a shower area roughly 32 inches wide and 60 inches long. That's enough room for a standing shower with comfortable shoulder clearance. Most guests won't feel cramped, and the space is easy to clean.
This size dominates in:
The downside? It's narrow. Taller guests or anyone with broad shoulders will notice. If your brand targets business travelers or luxury segments, 32 inches might feel tight.
This is the size that's becoming standard for newer hotel construction. Six extra inches of width makes a real difference.
A 36-inch wide pan gives you full shoulder clearance — someone 6 feet tall can shower without touching the walls. It feels more spacious, and the extra width reduces water splashing onto the bathroom floor.
You'll find 36x60 pans in:
The trade-off is space. A 36x60 pan needs a bathroom that's at least 5 feet wide. In a renovation, you might need to move a wall to make it fit. That adds cost.
The ADA requires a 36-inch minimum clear opening for roll-in showers. But the practical minimum pan size for a roll-in shower is 48x60 — that's enough space for a wheelchair user to transfer to a bench or shower seat.
Here's what ADA compliant means for pan sizing:
Most hotels designate 5-10% of rooms as ADA accessible. Those rooms need 48x60 pans. The rest of the property can use 32x60 or 36x60.
One thing to watch: ADA shower pans need proper slope to the drain — usually 1/4 inch per foot. The larger the pan, the more critical the slope calculation. A 48x60 pan that's not sloped correctly will pool water at the far end. That's a call-back waiting to happen.
ADA shower pans come in two main configurations:
Minimum pan size: 36x60, but 48x60 is the practical recommendation. The extra width gives the user room to maneuver a wheelchair or walker. The pan must have zero or near-zero threshold — usually a beveled edge no more than 1/2 inch high.
Roll-in pans work with a curtain or a door. If you use a door, it has to swing out (or be removable) so someone in a wheelchair can pull in and close it.
Transfer showers are smaller — 36x60 is standard. The user transfers from a wheelchair to a bench or seat inside the shower. The pan has a low threshold (ideally 1/2 inch or less) and grab bars on the control wall and adjacent wall.
Transfer showers take less floor space than roll-in, which matters when you're designing for ADA compliance within a standard bathroom footprint. But they require the user to be able to transfer independently — not all ADA guests can do that.
Zero-threshold pans are exactly what they sound like — there is no step up. The pan sits flush with the bathroom floor. This is the most accessible configuration, but it requires careful waterproofing and proper floor slope.
Zero-threshold pans work with linear drains along the back wall or center drains positioned so water can't escape. They're more expensive to install because the subfloor has to be recessed or the bathroom floor has to slope toward the pan.
Most hotel bathrooms were designed with tubs. When you convert to showers, the pan has to fit the existing footprint.
A standard tub is 60 inches long and 32 inches wide. That's the most common footprint in American hotels. Tub-to-shower conversion pans match this exactly — 60x32 — with the drain positioned where the tub drain was.
The offset drain is the key detail. Tub drains are at one end of the tub, not in the center. A conversion pan has to match that location or you're cutting into the subfloor and moving plumbing. That doubles the installation time and cost.
Most cast marble conversion pans come with offset drain options — left, right, or center — so you can match the existing drain location without extra work.
If your bathroom is a standard 5x7 layout, you have more options. You can use a 36x48 pan positioned diagonally, or a 32x60 pan against one wall. The standard 5x7 layout gives enough room to adjust positioning without moving walls.
Standard sizes cover about 80% of hotel bathrooms. The other 20% — older buildings, historic properties, odd layouts — need custom pans.
Custom shower pans are made to your exact dimensions. You send the measurements, the manufacturer builds a mold, and you get a pan that fits perfectly. Here's what that costs:
For projects under 20 units, custom pans might be worth it. For anything larger, the math works against you. You're better off adjusting the bathroom layout to accept a standard size.
Some manufacturers offer semi-custom options — standard lengths with custom widths, or vice versa. Wiselink, for example, can modify standard molds within certain ranges without charging the full custom mold fee. Ask your supplier about this before committing to a full custom order.
Q: What's the most common shower pan size in hotel bathrooms?
A: 32x60 inches. It matches the footprint of a standard tub and fits in most hotel bathroom layouts without requiring wall moves.
Q: Can I use a residential shower pan in a hotel?
A: You can, but you shouldn't. Residential pans aren't built for the traffic volume of a hotel. Commercial-grade pans have thicker gel coats, reinforced construction, and IAPMO certification. They cost more upfront but last 15-20 years instead of 5-7.
Q: What size pan do I need for ADA compliance?
A: A 48x60 roll-in shower pan with a 1/2-inch or lower threshold. Some configurations accept a 36x60 transfer pan, but 48x60 is the recommendation for full accessibility.
Q: How much does a custom shower pan cost?
A: Expect to pay 20-40% more than standard, plus a one-time mold fee of $300-$800. For a 50+ room project, the cost difference between standard and custom adds up fast.
Q: Do I need a linear drain or a center drain?
A: Center drains are standard for most hotel shower pans. Linear drains are used for zero-threshold or ADA configurations. The choice affects installation cost and pan price — linear drains add $50-$150 to the pan cost.
