Why to Put Your Tub in the Shower

Putting your bathtub in the shower may be an unexpected idea, but it’s a solid one and a growing trend in bathroom design.

Sure, it looks great, but what does it mean from a practical standpoint? For one, kids (and grown-ups) can splash all they want in the tub without having to worry about water damage or a mess. Two, the right tub model can double as a great shower bench or spot to perch your leg on while shaving.

Curious if this will work in your new bathroom? Take a look at these examples and learn what questions to ask your contractor before implementing this design.



Waterproofing is vital in these installations. Your bathtub will have a 1½- to-2-inch drain line that will need to travel through your shower’s waterproofing materials.

Tubs in general are awkward and a pain to hook up, so there are a lot of factors to consider here. For example: Will your tub’s anti-tipping brackets poke through your shower membrane? This is a good question to ask your builder.



If this modern tub were a tub shower, it’d be pretty difficult to waterproof because it’s designed as an undermount tub. Clean-lined tubs like this usually don’t have edging that connects the tub with the wall’s waterproofing. Placing the tub inside the shower means the entire area is waterproofed, and it actually simplifies the room’s design.

Tip: A typical shower’s glass door and fixed panels can cost up to $2,000. I like how this shower-tub combination has a single wall panel and no door. A simple design change like this can dramatically reduce the cost of your new bathroom.



Some tubs are a challenge to get into for people with knee or hip issues. If this is the case for you but you still want a tub, a combination like the one shown here can help with accessibility. This barrier-free shower allows for a tub, but the shower itself can still be used for years and years to come.

Tip: If you plan to wash your kids in the tub, place the shower fixtures so they can be used in both the tub and the shower to make things easier.



A built-in tub like this is actually much easier to install than a freestanding one. Waterproofing behind and under tubs with little wiggle room can be difficult, so I always suggest that clients install tubs like this, for practicality and cost savings.

Tip: Make sure your walls are waterproofed up to a height of 6 feet in your shower and tub area’s primary wet zone. Waterproof the walls at least 18 inches above the tub lip in a bathtub without a showerhead.
