The tub shower combo is the workhorse of American bathrooms. It saves space, serves families and keeps resale options open. But many owners debate whether to keep it, replace it or convert to a walk-in shower. This guide explains what a combo is, why people keep it, how replacement and conversion compare, cost ranges, hidden problems and how to decide. The search found nothing specific to a standard 60 by 30 by 60 inch combo, so cost figures here are general tub-to-shower numbers. This is not plumbing or construction advice.

What Is a Tub Shower Combo?

A tub shower combo has a bathtub and a shower in the same alcove, usually with a curtain or a glass door. The tub is typically about 60 inches long (general knowledge), which is why 60 inch shower rods and curtains are standard. See the shower rod guide. Types: One-piece fiberglass or acrylic unit. Fast and affordable. See the shower inserts guide. Tub with tile walls. Custom look. Tub with a surround panel kit. Walk-in tub combo. Has a door in the tub side for accessibility. Angi covers pros and cons of walk-in tubs.

Why Keep a Tub Shower Combo?

Soaking. A combo unit is the usual choice for keeping a soaking option, as one source notes. Kids and pets. Easy bathing. Resale. Buyers often want at least one tub in a house. (General real-estate view; check locally.). Space efficiency. One fixture does two jobs. Cost. Often cheaper than a custom walk-in shower.

Replacement Costs

Figures from the search, with caveats: One guide puts a combo installation starting around $1,000, not including removing the old unit. Another estimates a same-location alcove tub replacement at $1,500 to $4,000. Removing an existing tub has its own cost. One source says an ascot tub can be removed for around $200 to $300, depending on the material and size.

A prefab combo is the cheapest route. Step-in inserts and prefab kits are the quickest ways to reduce both cost and downtime. Keeping the same footprint is also the simplest option.

Converting to a Walk-In Shower

Costs and notes: One guide lists a walk-in shower conversion at roughly $4,000 to $10,000 for a basic tile, glass and fixtures setup. Another source gives a broader range: $4,500 to $12,000 total, depending on materials and scope.

Pros

It can make the room feel larger. One guide notes that swapping a tub-shower combo for a dedicated walk-in shower can free up enough room to add a double vanity or expand storage. It can help resale. One source says a large walk-in shower can be a major attraction to buyers. It improves accessibility. Level-entry designs remove step-over height. See the curbless shower guide.

Cons

You lose the soaking option. Conversion is more involved than it looks. It involves demolition, waterproofing, a new shower base or custom tile floor, walls, a glass enclosure and fixtures. Hidden problems can raise the price. Warning signs include damage during dismantling, hidden structural damage, potential water damage and pipe replacement needs.

See the shower pan sizes and corner shower guides for base options.
