Tub-Shower Combo Guide: Options, Sizes and Costs
The tub-shower combination is the most common bathroom fixture in American homes, and for good reason. In a standard 5x8 bathroom, it gives you a bathtub for kids and soaking and a shower for everyday use, all in the same 60-inch space.
TheRemodelers works with licensed bathroom contractors to help homeowners compare tub-shower combo options, sizes, and costs, and decide whether to keep a combo or switch to a walk-in shower. For remodeling costs across the whole bathroom, see our bathroom remodeling guide.
Tub-Shower Combo Options at a Glance
Option | What it is | Cost guide | Best for |
|---|
Tub with prefab surround | Alcove tub plus acrylic or fiberglass wall panels | About $2,000 – $4,500 installed for a new tub and surround | Budget remodels and quick updates |
Multi-piece tub-shower kit | Tub and wall sections that assemble in place | Similar to a prefab surround | Remodels where a one-piece unit won’t fit through the door |
One-piece tub-shower unit | Tub and walls molded as a single seamless piece | Lowest-maintenance option | New construction and additions |
Tub with tiled surround | Alcove tub with tile walls over a waterproof membrane | Costs more than panels; tile and waterproofing drive the price | A custom look and more design choice |
The installed range for a new tub and surround comes from HomeServe’s 2026 estimate for tub-shower combinations; a tub replacement alone averages about $2,100, according to This Old House, and a professionally installed surround about $1,100 to $2,100.
Standard Tub-Shower Combo Sizes
Most tub-shower combos are built around the standard alcove tub: about 60 inches long and 30 to 32 inches wide, with a tub depth of about 14 to 16 inches. Shorter tubs around 54 inches exist for tight spaces, and some combos run up to 72 inches long with deeper tubs for soaking.
Before choosing a unit, measure the wall-to-wall opening, the doorways and hallways it has to pass through, and the drain location. One-piece units are often too large to fit through an existing bathroom door, which is why remodels usually use a separate tub with panels or tile, or a multi-piece kit.
Choosing the Walls: Panels or Tile
Prefab Surrounds and Kits
Acrylic or fiberglass panels go up quickly, have few or no grout lines, and are easy to clean. A prefab surround costs about $500 to $2,000 for the unit. The trade-off is design: choices are limited to what the manufacturer makes.
Tiled Surrounds
Tile gives the most design freedom, including niches, accent bands, and any color or pattern. It costs more than panels and must go over a proper waterproof membrane, because tile and grout are not waterproof on their own. Large-format porcelain keeps grout lines to a minimum.
Doors, Curtains, and Fixtures
Shower curtain: the least expensive option and makes it easy to bathe children.
Glass doors or a fixed panel: a framed glass enclosure costs about $800 to $1,400 and frameless glass about $1,800 to $4,500. Sliding doors suit tub-shower combos best; a fixed panel keeps the tub easy to reach.
Shower valve: choose a pressure-balancing or thermostatic valve to prevent sudden temperature swings, and consider a handheld showerhead on a slide bar, which makes bathing kids and cleaning the tub easier.
A built-in niche keeps bottles off the tub ledge; plan it before tile or panels go up.
Tub-Shower Combo or Walk-In Shower?
Many homeowners consider replacing the combo with a walk-in shower. It can make the room feel bigger and removes the step over the tub wall. A prefab conversion typically costs $1,500 to $8,000, and a custom tiled walk-in shower $5,000 to $15,000. Our tub-to-shower conversion project shows what that involves.
The resale question matters, though. In the National Association of Home Builders’ 2021 survey, about 7 in 10 first-time buyers rated a primary bath with both a tub and a separate shower as essential or desirable. A common approach is to convert the primary bathroom to a walk-in shower and keep a tub-shower combo in the hall bath. For walk-in shower pricing tier by tier, see our walk-in shower cost and installation guide.
Turning a Shower Into a Tub-Shower Combo
Going the other way, adding a tub where a shower stall is now, is possible when the space is at least as long as the new tub, usually 60 inches. It usually means moving the drain, adding a new tub valve and spout, possibly reinforcing the floor, and redoing the walls. Have a contractor confirm the opening and drain location before buying a tub.
Tub-Shower Combos in Small Bathrooms
In a small bathroom, the combo is often the most efficient choice, because it puts two fixtures in one footprint. Clear glass or a light curtain keeps the room feeling open, and continuous wall tile or panels make the space read larger. Our small bathroom remodel guide covers where to spend and save in a compact room.
Final Thoughts
A tub-shower combo remains the most practical fixture for most family and hall bathrooms. Choose panels for speed and easy cleaning, or tile for design, and keep the plumbing where it is to control cost. If you are thinking about a walk-in shower instead, keep a tub somewhere in the house for resale.

Frequently Asked Questions
How much does a tub-shower combo cost?
A new tub with a prefab surround typically costs about $2,000 to $4,500 installed. A tiled surround costs more, depending on tile and waterproofing, and glass doors add about $800 to $4,500.
What is the standard size of a tub-shower combo?
Most are built around a 60-inch alcove tub about 30 to 32 inches wide and 14 to 16 inches deep. Shorter 54-inch and longer 66- to 72-inch options exist.
Is a one-piece or multi-piece tub-shower better?
One-piece units are seamless and easiest to clean but often won’t fit through an existing door, so they suit new construction. Multi-piece kits are designed for remodels.
Should I replace my tub-shower combo with a walk-in shower?
It can make sense in a primary bath, but keep a tub somewhere in the home. About 7 in 10 first-time buyers rate a primary bath with both a tub and a separate shower as essential or desirable, according to NAHB’s 2021 survey.
Can you convert a shower into a tub-shower combo?
