How to Replace A Bathtub (Step By Step)

In this video, you’re, going to learn how to replace your bathtub step by step, but more specifically how to do it from the top without having access to plumbing. From underneath alright let’s, go ahead and get started so before I walk you through this process, step-by-step, let’s, get familiar with some basic tub components.

How to Replace A Bathtub (Step By Step)

Alright. So here I’m drilling. This diagram for you and right here you have the bathtub looking at from the side view or the front view whatever you want to call it and bathtubs are pretty straightforward. Bathroom Remodel

They’re, usually in one piece, and they usually have this little flange right here – that’s used for two purposes: number one to keep water from getting back into the wall and number two. So you can attach the tub to the studs to secure the tub in place.

Okay and you’re, going to want to have the tub installed in a nice flat surface, and then you have the finished substrate, which is your tile or whatever. You’re, putting on there to finish the walls that actually hangs over top of the tub, so any water that might get on the walls or whatever just drains down and then goes into the tub and is able to drain out through the tub.

Instead of causing moisture damage to your home, okay and then you have the tub assembly, which is this area over here, which is composed of basically two drains. You’ve got your primary drain and then you & # 39.

Ve got your overflow drain and then they those both connect with this little t-connector, which feeds into a p-trap which then connects into your normal house, plumbing okay, so the water would flow down here through here.

This tub drain assembly actually comes in a kit, and that kit includes everything from the tub drain itself that you see with the finished material like brush, chrome or just Chrome or whatever it is, and then it comes with these little elit these elbows here this t-connector And then the pipes were here so this whole area right here is usually cut, usually comes in a kit, okay and then you would just be hooking into your existing plumbing.

That probably already has a p-trap. If you’re going to replace your bathtub, so when you go to purchase your bathtub, you’re, going to want to pay a 10 to do a couple of things number one! You’re, going to want to make sure you know the length of your bathtub.

Now, typically, most bathtubs come in five feet. Lengths: okay, they’re just five feet. You know they build houses, standard sizes to fit these bathtubs. It’s, usually 5 feet. The second thing you’re going to want to know is your drain side, which side is your drain on? It is on the right side, as you see here, or is it on the left side? So you need to know the length and right or left drain.

The second thing you want to consider is the material the tub is made out of tubs come in all kinds of different materials from cast iron to plastic. Now cast-iron tubs are typically gonna weigh about 300 pounds or even more so that’s, usually going to be pretty challenging to install for one person or even a group of DI wires right.

You might want to get a pro to do that, but you can also get like a lightweight plastic bathtub there’s, some really good options for that, and you can get a steel bathtub that’s powder coated, but just consider the Weight of that bathtub before you purchase it and finally, you’re going to want to consider the quality of the bathtub okay, some plastic bath tubs are really cheap and have been known to crack.

If you, when you tighten this drain down now, obviously that’s, not ideal, because in order to replace your bathtub, you have to rip out the finish material which could be really expensive tile or whatever.

It is either way it’s, not going to be ideal. It’s, not something you’re going to want to have to replace you’re, going to want to make sure to get a quality bathtub. So check online reviews read up, buy a quality brand, as you may have guessed there’s more than one way to install a bath tub.

So the normal way, the most common way, is to first connect to this entire drain assembly to the bath tub. And then you basically install that entire bath tub in in place make sure it’s, nice and flat and level in many cases, especially if you’re using like a cast-iron tub, you’ll, actually pour a mortar bed Down here before you set the tub and that mortar bed will actually support the bath tub, then you basically come up from underneath and then you hook up the plumbing, so you’ll at sometimes you’ll have to like cut into The ceiling, if there’s a floor below that or you’ll, have to get in the crawlspace or whatever you have to get underneath after the tub is installed to connect these pipes.

Okay, now, obviously that’s, not ideal. You don’t, want to cut into your ceiling down below and do a bunch of drywall in pairs and get your house all dusty. But in this video I’m, going to show you how to install your tub completely from the top.

So you don’t have to come up from underneath to connect these pipes later after the tub is installed. So hopefully, that’s, helpful! Let’s, go ahead and jump right into the installation to remove your old bathtub.

You’ll first need to remove any tile or other finished material around the tub, which I’ve already done here, then to remove the drain, grab a tub drain remover and twist it out this tool. Isn’t always necessary, but it certainly makes the job a lot easier.

You can find a tub drain, remover at most improvement stores and by the way for a complete list of tools and materials required and links to products that you can buy online visit DIY with Dan comm forward.

Slash bathtub then use a screwdriver to remove the overflow drain cutter next, remove the stud that secures the side tub flange on the side of the tub. That is opposite of the drain. This will give you the room necessary to actually remove the bathtub and install the new one.

Now this stud is usually installed perpendicular to the other studs and it’s, usually not a support beam. It’s there, specifically for the tub installation, so there’s, not gonna be a problem. If you remove it and then also make sure to remove any nails or screws that are securing the tub to the wall, then you should be able to lift the tub right out by lifting this tub.

The side of the tub that’s away from the drain and lifting up at an angle and then pulling the tub out that way. Now you can prep for the installation of the new tub. So first you’re, going to want to make sure the cutout for the drain is the proper size and is in the proper location.

According to the installation, instructions that came with your new bathtub make any adjustments as necessary. Then you’ll want to level the floor. Okay, this is important because it’ll, allow proper drainage from the tub and ensure a strong foundation to the tub, so it doesn’t crack or creak.

While you’re stepping in it now, there are two options to level the floor. You can pour a betta mortar and then set the tub while the mortar is still wet or you can level the floor. As you see me doing here, this takes more time, but it allows you to remove and reinstall the tub if you have a leak or if the plumbing doesn’t line out, I’m using an underlayment patch and skim coat by Henry to create a flat and level surface, as you see here once the floor has been leveled, go ahead and test fit the bathtub.

If your tub is surrounded with three walls, it’s, going to be a tight fit so purchasing a lightweight tub. Like the acrylic tub you see here makes the job a lot easier. Your tub should have solid contact with the ground on the entire surface, and it should also be level on all four sides.

You don’t want your tub sloping in either direction. However, just pay attention to the top of the tub because it’s, not completely flat. You know which is necessary for drainage, so make sure when you put your level on that, you put it on both edges of the tub.

As you see here, remove the tub again and make any adjustments as necessary until the tub is level and has consistent contact with the ground once the tub has been successfully test fitted, it’s time to build the drain assembly start out by installing The drain onto the tub and then the overflow drain, if you & # 39, ll, be setting your tub and a bed of mortar and connecting the plumbing from underneath.

Then you want to use a sealant to permanently attach the drain assembly right now. However, that’s, not what I’ll, be doing in this video. These tub drain assemblies are sold in kits that come with all of the plumbing fittings.

You need to build a drain. You can find these at most home stores. You will need to cut the pipes in order to make them fit. This is easily done with a miter saw, but you can also use a hacksaw if that’s.

What you have here, I’m using a razor knife to clean off any burrs created while cutting the pipe. Now it’s, important to make sure the pipes and fittings are clean and free of burrs. Before you look once you’ve dry, fit the drain assembly, take some ABS glue and glue the drain assembly together by using the applicator to liberally apply glue to both the inner surface of the fittings and the outer surface of the pipes you’ll want to work quickly, since this glue sets up fast, and you will also want to hold each connection for about 30 seconds to make sure it has a solid bond make sure the drain fittings are installed in the right direction as well.

So the water can drain easily and then wipe off any excess of glue. Let it sit and you’re, ready to move on. So, in order to position our drain correctly, we’re. First gonna want to install a temporary piece of wood that we’ll use to mark the location of the drain, then put the tub back into place and Mark the location of the drain on that piece of wood.

Try to be as precise as possible. You also want to measure from the top of the temporary piece of wood to the bottom of the tub, where the drain will contact it. So you know how high to install the drain, remove the tub again and transfer the drain location to the floor.

As you see me doing here then measure the height of the drain, based on your previous measurement, while the tub was in place and make sure to consider the height of the rubber gasket that sits between the tub and the drain for this installation.

This two-inch wood block is the exact height that I need the drain to be at so it’s, a perfect tool for me to use when I’m positioning the drain later so go ahead and remove the temporary piece of wood And now it’s time to install the drain assembly using the marked locations so carefully, dry-fit the drain assembly.

So it lines up exactly where you want it to be. You need to be as precise as possible here and again. You can see how I’m lining it up with this wood block. To make sure I get the correct height, which is really important and again make sure to consider the thickness of the rubber gasket, and then you could go ahead and glue them into place using the ABS glue like we did earlier.

You really want to take your time here to get the drain position correctly, or it won’t line up with the tub, and you’ll have to do it all over again. All right. Now we’re ready to install the tub so before you do you’re gonna want to test fit the tub one more time to make sure the drain assembly lines up with the bathtub.

If it does line up now, we can proceed so take the tub out and apply sealant to the overflow drain. Gasket for some extra insurance against leaks also apply that same silicone sealant between the drain and the gasket, and on the top of the gasket, to create a seal to the tub, be careful here and just apply a small, consistent bead of the silicone sealant around the Outer edge here so that none of the sealant gets inside of the threads.

While you’re trying to screw in the tub drain now you can carefully move the bathtub into place being careful not to smear the silicone sealant. Once you have the tub in place, if necessary, add some more sealant and then install the overflow drain cover, add one more thick bead of silicone sealant to the underside of the drain flange and to the tub itself and then screw in the tub drain.

Tighten it really well using a tub drain. Remover, just don’t, go so tight that it breaks the tub or the drain. Now, the first time I did this, I didn’t, tighten it enough and I had to end up installing the whole tub again because I tested it and it was actually leaking and I had to go through this entire process again.

So don’t do that, then you can wipe away any excess, sealant and then screw in the drain. Stop now you’re ready to secure the tub to the wall. Pre-Drill holes in the tub flange using a 3/16 inch drill bit at every stud location.

Now you can reinstall the stud you removed earlier to remove the old tub, then use one and five-eighths inch panhead screws to secure the tub to the wall, use shims wherever there is a gap between the studs and the tub.

So you don’t. Put too much pressure on the tub, flange and break it all right, you’re, almost done so wait for one day for the sealant to set and then test the tub for leaks by filling it up and then listening for dripping sounds you don’t want to listen really closely to hear any dripping sounds even go below the tub as possible.

To listen for dripping sounds down there to make sure there’s, absolutely no leaks. If you’re free and clear of leaks, use a sealant to caulk the tub where it meets the floor and you’re all done.
