How to Replace a Bathtub (Step By Step)

In this video, you'll learn how to replace and install a new bathtub in your bathroom.

You'll learn how to remove an old bathtub, how to choose a new bathtub, and how to install a new alcove bathtub. You'll also learn all about bathtub plumbing.

First, I'll show you exactly how to remove your old bathtub and disconnect the drain and plumbing.

Then, I'll show you how to level the floor and prep the floor for a new bathtub so you have a level and flat surface to support the tub.

Then, I'll show you how to build the bathtub drain assembly and connect it to the tub.

And finally, you'll learn exactly how to install the tub, hook up the plumbing, seal the drain with silicone drain sealant, and secure the tub with the wall with bathtub screws.

I get a kick out of the guys who think unless you are licensed, you are incapable of doing anything. Maybe I should get a license to change a light bulb. Remember the saying; You can't please all the people all the time (and why even try). Dan does a nice job of explaining how to install a tub and I'm sure that he appreciates constructive comments on ways he can improve, as nobody is perfect. It's very low class when you have jerks, professional or otherwise, make denigrating comments about how you do things ( as if they were perfect). Keep the vids coming, dude and don't let negative comments make you down.

I realize this video is three years old but you just saved me a huge hassle with your drain marking tip and your “remove the stud trick.” Thank you very much.

Not big on commenting on videos, but this one is by far the best I've seen, including commercial company's. Bravo and thank you.

Best and most complete tub install video by far.. one thing everyone missed is the stud that is there to be removed to make room for the tub to fit.. great job

[suzannebownik]

Oh my gosh! You saved me so much headache and I wish I would have viewed this before trying to fit the tub in the first time! The 2x4 installed just for the flange gave me a sore back. 2x4 removed, smooth as butter!!! Thank

Great video, glad to see you used silicon instead of plumbers putty. A lot of plumbers dont realize that putty drys out and cracks, only good for 5-10 years. Had to fix so many drains because of it.

I want to thank you for taking the time while you’re working and filming this helping people learn something new and God bless and stay safe

I am about to hire a contractor to renovate my bathroom and did not know the correct bathtub installation procedure. After watching your excellent & informative step-by-step video I will now be able to spot-check the contractor and be able to determine if the installation is being done correctly. Thank you for your excellent how-to video !!!

[jasonwatzka]

I've been doing this for many years, and have an upcoming install with no access. Your template idea is a lifesaver! Tha ks for the clear and concise video

[billmitseff]

This is the absolute best video exposing a bathtub install. Thank you.

[kylefulks]

Really enjoyed your whiteboard session/explanation before showing the step by step installation. Very helpful!!

[forhisglory]

I know nothing about installing bathtubs, but this tutorial was amazing.
I'd probably still screw up, but this video would still motivate me to give it a go. Thanks.

[dormanpujols]

Excellent video, no one else shows how to remove a tub and install it like that, thanks.

You are an AMAZING instructor!! Love the drawings of the behind the scenes tub!! Helps tremendously to understand better and to know what we are working with!! I've watched the whole bathroom reno series a million times to get it solid in my head. With your excellent tutorials, I'm feeling confident I can do this!!

Mahalo nui(much thanks) from a humble gal in Hawaii. Wish me luck embarking on a bathroom reno!!

[guygriesmann]

Great viseo for installing a bath tube. O have done in new construction, but never in a remodel situation. I appreciated your discussion about being able to remove the old tub and bringing the new one in at an angle. This will apply to my next job. Thanks.

[madonnahagedorn]

Thank you! Your tutorials are very clear and easy to understand. You take the guesswork out of this project that might otherwise be very intimidating!

[MohSheir]

I love the sideview drawing explanation, very useful video

[idadho]

When inserting the ABS joints, ALWAYS MAKE AT LEAST A QUARTER TURN. the spread the solvent cement to prevent leaks.
