A 48 x 36 shower pan is a standard alcove-size shower base built for three-wall installations, and prices in 2026 run from about $270 for a basic acrylic pan to over $1,700 for a tileable kit with a bench. Most models ship with a center drain, though off-center options exist for tight bathrooms.

What Fits a 48 x 36 Shower Pan
48 x 36 means the pan measures 48 inches along one wall and 36 inches along the other. It’s one of the most common shower base sizes for a standard alcove, the three-wall shower opening found in most homes built after the 1970s.
This size works well for a primary bathroom remodel where you want more room than a 32 x 32 corner unit but don’t have space for a curbless walk-in shower. Measure your rough opening before you order. A pan built for 48 x 36 will not fit a 47 x 35 or 49 x 37 space without cutting or shimming.
48 x 36 Shower Pan Cost by Material
Price depends mostly on the base material and the drain style. Acrylic and fiberglass pans cost less but limit your finish options. Tileable pans cost more upfront but let you match tile to the rest of the bathroom.
| Type | Typical Cost Range | What Affects the Price |
|---|---|---|
| Acrylic, center drain, single threshold | $270 – $680 | Brand, drain finish, curb style |
| Solid surface or composite base | $600 – $1,000 | Slip resistance rating, color, drain grate |
| Tileable, ready-to-tile foam or fiberglass base | $380 – $900 | Pre-pitch quality, included drain assembly, curb height |
| Tileable kit with integrated bench | $1,100 – $1,700+ | Bench size, extra wall flashing, drain type |
These are national averages, not local quotes. Regional freight costs and retailer markup can shift the number by $50 to $150 in either direction, so treat this table as a planning range.
Center Drain vs Off-Center Drain Placement
A center drain sits in the middle of the pan and works with most existing plumbing rough-ins. Left-drain and right-drain versions shift the drain toward one wall, which matters if your existing waste line doesn’t line up with a center location.
Check your rough-in drain location before you order. Moving a drain line after the pan arrives usually means opening the subfloor, which adds real labor cost. If you’re not sure where your current drain sits, a licensed plumber can confirm it in about 15 minutes.
Acrylic vs Tileable Shower Base Options
Acrylic and fiberglass pans arrive finished. You install them and hook up the drain, no tile needed on the floor itself. They’re the fastest option and the cheapest, but the color and texture are fixed at the factory.
Tileable pans give you a flat, pre-sloped surface designed for thin-set mortar and your own tile choice. Manufacturer data for these pans typically lists a factory pre-pitch of about 1/4 inch per foot toward the drain, which is the standard slope used in most plumbing codes to prevent standing water.Each pan is built to slope ¼” per foot per plumbing code, channeling water directly to the drain, which prevents ponding and reduces maintenance Local code details can still vary, so check with your local building department, also called the AHJ, before you finalize a tile plan.

What’s Included in a Shower Pan Kit
A basic pan usually ships alone, with the drain grate as the only extra. A full kit adds more.
- Drain assembly, often a 2-inch PVC compression fitting
- Drain grate in a chrome, matte black, or brushed nickel finish
- Tile adhesive or thin-set, on some tileable models
- Integrated curb and splash walls, on one-piece tileable pans
- Bench, on combination pan-and-bench kits
Read the product listing closely. Some kits list tile adhesive as included, while others expect you to buy modified thin-set separately from an approved list in the instructions.
Shipping and Delivery for a 48 x 36 Shower Pan
Most shower pans in this size ship by standard parcel carrier, but heavier tileable bases and bench kits often go by freight truck. Freight delivery usually means curbside drop-off, not placement inside your home, so plan for two people to move a 40 to 70 pound pan.
Inspect the box for crushing or water stains before you sign for delivery. Shipping damage is far easier to resolve at the door than after you’ve opened the box and started a return. If the pan looks damaged, note it on the delivery receipt and photograph it before you sign.
Retailers vary on return windows and restocking fees for oversized items. Contact customer service before you order if you’re not sure whether the retailer offers a refund or exchange on a damaged shower base, and keep your order confirmation until installation is done.
Installing a 48 x 36 Shower Pan
Acrylic pans set on a bed of thin-set or mortar for support, then connect to the drain with a compression fitting or solvent weld, depending on the drain type. Most manufacturers recommend a full mortar bed under the pan, not just foam blocks, to prevent flexing and cracking over time.
Tileable pans install the same way, then get thin-set and tile directly on top once the pan is set and the drain is tested for leaks. A flood test, filling the pan with an inch or two of water and checking for leaks over 24 hours, catches problems before tile goes down.
You can handle the pan-setting and tile work yourself if you’re comfortable with basic plumbing connections and tile work. Call a licensed plumber if the drain rough-in needs to move, if you find signs of an existing leak in the subfloor, or if local code requires a permit for the drain work in your area.
Common Mistakes When Ordering a 48 x 36 Shower Pan
Buyers often order by the size printed on the old pan instead of measuring the actual rough opening, which can be off by an inch after years of settling or a prior remodel. Measure twice, at the top and bottom of the opening, since framing isn’t always perfectly square.
Another common mistake is skipping the drain location check. A pan built for a center drain won’t work on a rough-in built for a left-drain layout without moving plumbing. Confirm drain placement and curb height against your existing framing before you place an order, not after it arrives.
Choosing the Right 48 x 36 Shower Pan
For a straightforward remodel with an existing center drain, an acrylic 48 x 36 shower pan in the $270 to $680 range covers most standard installs. If you want tile on the shower floor to match the walls, a tileable pan in the $380 to $900 range gives you that flexibility for a moderate cost increase.
Confirm your rough-in drain location, measure the actual opening, and check the retailer’s damage and return policy before you place an order. Those three checks prevent most of the return and installation problems homeowners run into with this size pan.
Shower Pan FAQs
Does a 48 x 36 shower pan work with a standard bathtub-to-shower conversion?
Yes, in most cases. A standard tub opening is close to 60 inches long, so a 48 x 36 pan usually needs some wall framing adjustment to center it in the space. A contractor can confirm whether your specific opening needs modification.
Can I cut a tileable shower pan to fit a slightly smaller space?
Some tileable pans, especially foam-core models, can be trimmed on site according to manufacturer instructions. Acrylic and fiberglass pans generally cannot be cut without weakening the base, so check the product spec sheet first.
How heavy is a 48 x 36 shower pan for delivery?
Weight varies by material. Acrylic pans typically run 15 to 25 pounds, while solid surface and mud-bed tileable kits can weigh 40 to 70 pounds or more, which is why many ship by freight rather than standard parcel.
Do I need a permit to replace a shower pan?
That depends on your local building department. A straight swap with no plumbing changes often doesn’t need a permit, but moving a drain usually does. Check with your local AHJ before starting the project.
What’s the difference between a shower pan and a shower base?
The terms are used interchangeably by most retailers and manufacturers. Both refer to the floor component of a shower, whether it’s a finished acrylic unit or a tileable base you finish yourself.
