If you’re thinking about installing a new bathtub, there are a few things you should know before taking on the project. First, it’s important to note that bathtub installation is best left to experienced professionals. While some DIYers with plumbing or construction experience may be able to complete the job, it’s always best to err on the side of caution and call a plumber.
They will install your bathtub in accordance with code, ensuring a safe and efficient process. Installing a bathtub is not a quick or easy process. It generally takes several hours, so make sure you have plenty of time set aside to complete the job. You’ll also need a few tools and supplies on hand, including:
– A screwdriver
– A hammer
– A drill
– Piping (for drainage)
– Caulking
– Tile adhesive (if you’re installing a tile surround)
Once you have everything you need, the first step is to remove your old bathtub. This will involve disconnecting the plumbing and draining the tub. Once that’s done, you can move on to preparing the area for the new tub. This includes ensuring that the subfloor is level and attaching any brackets or supports that may be required.
With the area prepared, you can now start installing the new tub. This involves connecting the drain and overflow pipes, as well as the water supply lines. Once that’s done, you can test for leaks and then caulk and finish the install.
How to Install a Bathtub?
Whether you’re doing a complete bathroom renovation or simply replacing an old bathtub, following these steps will ensure a successful installation. And, as always, if you have any doubts or questions throughout the process, don’t hesitate to call a professional. They can help you avoid any potential problems and ensure a safe and efficient installation.
Step 1: Remove the Existing Bathtub
The water supply must be turned off before working on removing an old bathtub. Turn on a faucet below the level of the bathtub to drain out any remaining water after you turn off the water. You can begin working after the water stops flowing. Taking out the tub from the wall is as easy as removing the faucet and handles. Your tub will have to be removed by removing part of the wall, removing the piping, and sliding it out.
Step 2: Choose the Right Bathtub
A replacement bathtub should be precisely the same dimensions as your old one as well as have the drain and faucet on the same side. So your piping system won’t have to be changed and the sink will fit in the same place. Identify the style of your bathroom and choose a tub that matches it.
Step 3: Ledger board and plumbing installation
Your new tub’s plumbing will be complete with a tub drain kit you can purchase at a hardware store. To install the plumbing in the new tub, follow the instructions that came with the kit, and then measure your bathroom plumbing to make sure your new tub will match your bathroom plumbing.
Adjustments may need to be made if it does not. The wall behind some bathtubs needs to be fitted with a ledger board to help support the tub. It should be installed at the appropriate height according to the instructions that came with your new bathtub. Depending on how old your old bathtub was, and its condition, you may be able to adjust the height of the old bathtub to match the new one.
Step 4: Install the Bathtub
Installation of the new bathtub can begin once the plumbing and ledger board are complete. Take care not to damage the tub, the wall, the plumbing or the ledger board in the process of lowering it into place. This step, which involves aligning the bathtub exactly, is best done with the help of someone since bathtubs are heavy. If you want to ensure your tub is level after it’s in place, use a bubble level instead of guessing.
Since many tubs are designed with sloped bottoms, place the level on the top edge of the tub, not the bottom. The ledger board should be adjusted and the bathtub shifted until it is level. The tub should be attached to the wall studs with screws once it’s leveled. Use the holes that were pre-drilled in your bathtub’s upper flange, but be careful not to over tighten them.
Step 5: Hook up the Plumbing
It is time to connect the bathtub to the plumbing system now that it has been installed. Afterward, install the overflow and drain flanges, followed by the shoe fittings under the tub and drain pipes. These pieces will be installed according to the instructions included in your tub plumbing kit.
Step 6: Bathroom Surrounds should be installed
With a bathtub surround, you can prevent water damage to the walls around your bathtub and give it a more finished appearance. In order for the adhesive to hold the surround securely, the wall must be clean and dry before installing one. Next, mark the dimensions of the surround on the wall above the tub. Use the surrounding adhesive according to the directions included with it. Once the adhesive has been activated, hold the surround against the wall for about three minutes, then pull it away and reapply it. If the adhesive has any special instructions on the package, make sure you check them.
This is the most common method of applying adhesive. Mineral spirits can be used to remove excess adhesive from the surrounding sides. Once the adhesive has dried, hold the surrounding panels in place with masking tape. In the gaps between the bathtub panel and the surround panels, use silicone to seal all cracks. The process of installing tile over your bathtub will be very similar to that of installing a bathtub surround.
In order to make sure each tile is evenly spaced, you’ll have to measure and cut them individually. The gaps between the tiles will then be filled with grout. Before you turn the water on and start using your newly installed bathtub, make sure the adhesive and silicone have completely dried.
You can install your own bathtub in just one weekend if you follow these steps and follow the instructions that come with your supplies.

They can be placed under the bathtub’s feet in order to level it out and make it more stable. Another way to stabilize a bathtub is to use an adhesive caulk. Adhesive caulk can be used to secure the bathtub to the floor or wall, which will help prevent it from moving around. If you are unsure about how to properly stabilize your bathtub, you should consult a professional for assistance.
Do you put a cement board under the bathtub?
You should always put a cement board under a bathtub, regardless of the type of tub you’re installing. The cement board provides a solid surface for the tub to sit and helps protect against water damage. If you’re installing a cast iron or steel tub, you’ll need to use a 1/2″ thick cement board. For acrylic or fiberglass tubs, you can use either 1/2″ or 5/8″ thick cement boards.
Installing cement boards is a fairly straightforward process. First, measure the area where the tub will be installed and cut the cement board to size using a utility knife or circular saw. Then, attach the cement board to the subfloor using screws and washers. Be sure to countersink the screws so they’re flush with the surface of the cement board. Once the cement board is in place, you can proceed with installing your tub.
Can I use spray foam under my tub?
No, you should not use spray foam under your tub. Although spray foam is an excellent insulator, it’s not meant to be used in wet areas like around a bathtub. If spray foam gets wet, it can expand and cause damage to your tub or bathroom.
Does a tub have to be perfectly level?
No, a tub does not have to be perfectly level. In fact, most tubs are installed with a slight slope so that water will drain properly. However, the tub should be level enough so that you can’t see any gaps between the tub and the wall when it’s installed. If your bathtub is not level, you can use shims to level it out. Simply place the shims under the tub until it’s level, then secure them in place with screws.
My bathtub is leaking, what should I do?
If your bathtub is leaking, the first thing you should do is check the caulking around the perimeter of the tub. If the caulking is cracked or missing in places, simply remove the old caulking and apply new caulking in its place. Be sure to use waterproof caulking that is specifically designed for bathrooms. If the caulking does not fix the leak, you may need to replace the tub’s drain assembly.
To do this, you’ll need to remove the tub and access the drain from underneath. Once you have access to the drain, unscrew it and replace it with a new one. If you’re still having trouble with your bathtub leaking, call a plumber for assistance.
Does a bath need a frame?
A bathtub doesn’t necessarily need a frame, but it’s always a good idea to install one. A frame gives the tub extra support and helps prevent it from moving around when you’re using it. It also makes it easier to install the tub, since you won’t have to worry about holding it in place while you attach it to the wall.
How high should a bath be off the floor?
There is no definitive answer to this question, as it depends on your personal preferences. However, most bathtubs are installed approximately 14″ off the floor. This gives you enough clearance to get in and out of the tub without having to step over a high edge. It also helps prevent water from spilling onto the floor when you’re taking a bath.
Do I need to use primer before painting my bathroom?
Yes, you should always use primer before painting a bathroom. Bathrooms are high-moisture areas, so they require a special type of paint that can withstand humidity and condensation. Primer helps the paint adhere better to the surface and provides a barrier against moisture.
