Notice how Steve drew a line along the subfloor. This indicated the rough location of the tub waste pipe. Shooting a nail through that would totally ruin our day!! We needed to add a second layer of subfloor. But in order to do that we spread more Liquid Nail on top of the first layer of subfloor.
Once the subfloor is prepped, dry fit your new bathtub and check the walls for plumbness. We had to build both a knee wall and the main wall. This old bathroom was a pain in the butt. None of the walls were plumb or straight.
So we dry fit the tub and centered it on the plumbing wall. After making the tub square with the adjacent walls we made a mark on the plumbing wall and on the plywood behind the tub. He measured from the front of that stud to the mark he made on the plywood behind the tub.
Once this is in place you can run your studs from it to the existing framing. Studs should be at least 16 inches on-center and plumb since the tub will be attached to them. The 16 o. Cut an elliptical shape out of the subfloor for the drain. Use either a jigsaw or reciprocating saw. We had a bit of an issue in this project as a portion of the joist was below the drain. This can make or break your project. The Kohler Archer bathtub requires a special overflow drain kit.
It actually makes the tub look pretty cool. We recommend putting the drain assembly together first before securing your tub to the studs. This makes the installation easier…and lessens the likelihood of you tearing out your hair just keeping it real.
He added the silicone to the overflow then bonded the rubber gasket to it. He then adds another bead of silicone to the tub where the overflow will go. And a silicone bead directly on the part of the gasket that will attach to the tub.
And yes, Steve loves clear silicone almost as much as coffee. Kohler provides a bracket to hold the overflow in place. Use a screwdriver or impact driver to secure the bracket to the overflow. If you use an impact driver just be careful not to overtighten as this can crack the tub which would be super BAD.
Then screw on the PVC pipe fitting. The nice part about this Kohler Clearflo kit is the flexibility of the pipe fitting to move.
Steve does the same silicone procedure with the tub shoe and drain. All parts get a nice bead of silicone. To see the detailed plumbing installation start watching the video at the mark. There are a lot of great tips. One of the biggest mistakes DIYers can make when installing this kind of tub is to not set it in mortar. Steve always has the best material suggestions. And this tutorial is no exception.
Usually you need one 55 lb of mortar for one tub. Mix the mortar so that it can support the tub. The mortar should be evened out and about 2 inches thick on all sides.
Then embed the tub into the mortar. Pre-drill holes in the tub lip. The holes should correspond with the stud locations. Once the tub is level you can attach it to the studs using 2 inch galvanized screws. Place your foot on the inside edge of the tub to hold it steady while securing one screw in the center of the tub on the main wall. Check the tub is level again on the main wall then transfer your level to the front of the tub.
Push the tub down into the mortar to get a level position and secure one screw through the tub lip and into the stud. Do this for the back wall as well. Otherwise you could break the tub lip when you secure it to the stud. Watch our video to see all the awesome tips.
Steve and I wanted this to be the best installation video for an acrylic bathtub. If you want to learn how to install an acrylic bathtub this video and tutorial should help a TON. Thanks for reading, watching and adding your thoughts to the comments. Do ask any questions down below. Question 10 months ago on Step 6. Question 2 years ago. The Kohler installation instructions say to use furring strips and to 'Install water-resistant wallboard over the framing' shows a picture of it overlapping the tub flange.
Place a gasket around the strainer from the outside of the bottom of the tub, then screw the strainer to the drain chute, which a long pipe that includes the overflow drain. Connect the overflow drain. Slip the trip lever stopper and linkage through the overflow drain opening on the inside of the tub. Use a screwdriver to secure the overflow cover with the trip lever to the inside of the tub. The stopper and linkage go inside the pipe to stop or allow the flow of water.
The overflow drain will prevent the tub from overflowing if you leave the water running as it directs the water into a drain pipe. Part 3. Set the tub in place and level it. Carefully position the tub in the alcove so that the drain rests over the drain opening in the floor. Place a level on each side of the tub. If any spots are uneven, position hardwood shims underneath the tub and glue them in place. Secure the tub to the studs. There will be a small flange, or vertical lip, around the outside of the tub.
In most cases, you can use a hammer to drive roofing nails through the flange to secure it to each stud in the wall. Fit a new tub surround. The surround is made up of the panels that protect the wall around your tub from moisture and mildew.
First, dry-fit the surround and mark the location of the accessories, including the faucet and water handles. Ensure that the faucet will line up with the water lines in the wall. Then, cut out the accessory openings with a jigsaw.
A one-piece surround is the easiest type to install. Caulk the tub to the surround and secure the surround to the studs. Place a bead of silicone caulk around the entire perimeter of the tub on the ledge next to the flange. Then, carefully set the surround on top of the silicone caulk. Next, use a drill to screw the surround into each wall stud. Aim to use a screw every 6 inches 15 cm up the length of the surround. Connect the water lines and install your accessories.
Screw the faucet into the coupling for the water lines through the hole in the surround. Then, screw the strainer cover over the drain opening in the floor of the tub. Add any other accessories you need, such as handles if they are separate from your faucet. Connect the drain to the P-trap. Thread the drain chute into the P-trap under the tub.
Caulk the tub to the floor. Run a bead of silicone caulk along the outside edge of the tub where it meets the floor. Make sure it meets both outside corners to prevent water from getting in between the tub and floor. Smooth out the bead with your finger or a damp rag. Wait 24 hours before turning on the water. To give the caulk and other adhesives time to dry, wait at least a full day. Then, you can turn on the water and check for leaks.
If you find any problems, contact a certified plumber. Yes, I do, cement-board actually. Never use ANY drywall in any bath. Many manufacturers say skip it and attach or seat directly to the framing. This isn't remotely ideal for humidity containment nor for insulation or sound dampening. You never want framing directly exposed to any future potential water leakage, water always wins. Not Helpful 6 Helpful I want to put a bath tub in.
I live on the 4th floor and currently only have a shower. Can I use the same drainage hole for the bath that is already there for the shower? Not Helpful 1 Helpful 2. If I'm installing a fiberglass surround bathtub. Do I have to put a cement board behind it? It can be attached directly to the studs. Where the flange is, all around the tub, should be set into the studs the thickness of the flange so the wall board around it will be flat and against the studs everywhere.
Drill the flange for the screws so you do not crack the fiberglass. Doing that will keep the wall along the bath surround flat everywhere. Be sure that those walls are insulated. Also be sure the bottom of the tub is supported with concrete that is mixed with peanut foam. Insulate the rest of the bottom of the tub. Insulation will keep the bath water warmer longer.
My wall is six foot wide all the way to the door, how do I turn it to get it out the door? You cut it in half or more.
It's garbage and should be treated as such. It may have been installed before any other fixtures or before there was even a hallway railing or any walls and doors. Not Helpful 4 Helpful 1. Zero, if you mean how close should the tub be to the wall. Otherwise, a minimum of 1 inch if you're talking about a short or half wall running just beyond the tub and enclosing the tub area.
If you're tiling and have room to extend the wall into the room, then you may want the tile width or half-width dictate the spacing so that tiling is much easier and better looking. Not Helpful 3 Helpful 2. Whatever and wherever your instructions say to. Manufacturers that use those things have very specific and finite spots where they must go, using only the exactly specified screws. Not Helpful 6 Helpful 2. I'm replacing my tub, but since I have to bring it in at an angle due to limited space, how do I get it into place?
You'll just have to win the wrestling match. They don't install themselves and no one said it was always easy. You may even have to walk it in literally a millimeter at a time on either end. You can also remove wallboard, doors, door jambs, cabinetry, and toilets.
Not Helpful 4 Helpful 6. Drew Hawkins1. If the tub fits easily into the space and the plumbing is already set up, you can install it yourself. Install a ledger board on the wall, put the tub in place, and make sure it's level.
Secure the flanges to the wall studs and fit the tub surround into the space. Caulk the surround and any cracks so the area is sealed. Then, you can connect the water line. Not Helpful 1 Helpful 3. Installing a new bathtub is a challenging task that needs to be done correctly so there won't be water damage. You'll need to be prepared to repair any tiles that are damaged in the process as well. Bathtubs are also generally pretty heavy, which means removing the old one and installing the new one can be an arduous task.
If you're unsure of your ability to correctly install a bathtub, your best bet is to hire a qualified plumber or contractor. Not Helpful 1 Helpful 1. It depends on your preference, but according to Hygiene Expert, a shower is a better way to get clean if you're really dirty.
But, if you're just getting clean from a normal day, a bathtub will get you just as clean. A shower usually uses less water than a bathtub as well, making it more environmentally-friendly. As far as installation, the price of purchasing and installing a shower or a tub is about the same.
