How To Make a Shower Pan

Making your own shower pan allows you to modify the size and shape to fit your needs.Spread mortar so it leads to your drain when you frame out your shower pan.If you want to put down tiles, you need to add a waterproof liner and a second layer of mortar.In a few days, you will have a shower pan that won’t leak.

Step 1: 2 by 6 inches boards are used to frame out the shower pan.

Write down the distances between the studs on the walls where you plan to build your shower pan.You can use a circular saw to cut boards that are 2 by 6 inches.The cut boards should be positioned between the studs in your walls and the bottom plate of your wall frame.You can ask the employees to cut your board for you if you don’t have a circular saw.

Step 2: 2 in 4 in boards are used to build a curb for the shower pan.

The curb is where you would step into the shower if you were in a pan.You can find the length of the shower area that doesn’t have a wall.Put a 2 in 4 in board on top of the subfloor and nail it into it.Put 2 more boards on top of the first one and nail them in place.

Step 3: The tar paper should be secured to the floor.

Tar paper protects your shower pan from water.Take a sheet of tar paper and lay it on the floor of your shower pan.To keep tar paper in place, drive a nail into the floor every 8 inches.Tar paper can be purchased from your local hardware store.Make sure the tar paper pieces overlap by at least 2 inches.

Step 4: There is a hole in the tar paper.

The tar paper can be used to locate the drain on the floor.You can cut through the tar paper by following along the edge of the drain.If you want to keep tar paper out of the drain, try to stay as close to the edge as possible.Hire a plumbing professional to install the pipes for you if you don’t already have a floor drain in place.Make sure you have a lower and upper part of the drain.You can find 2-part drain at your local home improvement store.

Step 5: To keep mortar out of the drain, tape it closed.

You can cover the opening on the drain with pieces of duct tape.To completely cover your tape, overlap it by 1 inch.You can apply mortar to your shower pan if you protect the drain with tape.You can put a cloth into the drain pipe if you don’t have duct tape.

Step 6: It is a good idea to mix mortar.

Put a bag of quick-set mortar into a mixing tray and spread it out evenly.Put in a small amount of water at a time and mix the mortar with a garden hoe.Aim to use 1 part water for every 4 parts of mortar mix.Put the mortar into a ball and squeeze it with your hands.If the water comes out, use more of the mortar mix.It will be hard to apply your mortar since it won’t hold its shape.The shower pan’s size affects the amount of mortar you need.You need 2 bags of mortar for a 4 ft shower pan.

Step 7: A thick border is needed around the frame of the shower.

You can spread the mortar around by dumping it on the tar paper.Use a flat trowel to push and shape the mortar into a border around the shower that is 1 2 inches thick and extends out from the frame.Press down on the mortar to make sure there are no air pockets.It is easier to slope later on if the border is shaped first.

Step 8: Spread and smooth out the mortar.

When you have a border around the edge of your shower, you can start smoothing out the mortar.Start from the corner furthest away, so you don’t disturb any of the mortar you’ve already worked on.The mortar should be Sloped so that it drops 4 inch (0.64 cm) between the wall and the drain.The first layer of mortar needs to have the correct slope in order to move on.If you don’t apply the entire layer of mortar in a day, it will dry unevenly.

Step 9: Before removing the tape, let the mortar dry for at least 24 hours.

Leave the mortar alone overnight so it can set once smoothed out.It takes about 24 hours for the mortar to be set.Remove the tape covering the drain when the mortar is dry.

Step 10: The shower liner should be 2–3 in taller than the framing.

Another layer of protection for your subfloor is the shower liner.Measure the size of your shower pan and add 8 inches to each side to account for the framing on the side.To cut the liner, use a utility knife.You can buy shower liners at a hardware store.

Step 11: There is a bead of Silicone.

If you want to apply your sealant to the shower pan, you should put it in a silicone gun.You can apply a thin bead of silicone by following along the outer rim of the drain.The liner is held in place by the silicone.Silicone sealant can be purchased from your local hardware store.

Step 12: It is a good idea to put the liner inside your shower pan.

Slowly lay the liner on the mortar and smooth it out.The shower liner should be aligned so that the edges extend past the 2 in 6 in frame.Push the liner tightly around the edge of the mortar.The liner should stick to the bead you applied it to.

Step 13: Attach the liner to the wall studs with nails or staplers.

It is better to nail the top edge of the liner to the wall studs.To secure the liner in place, use roofing nails or woodworking staplers.Make sure the liner stays smooth on the floor by working your way around it.

Step 14: The liner has holes for the drain.

You can find the drain hole and bolts from the liner.You can access the holes and bolts by cutting X-shapes into the liner.The liner should be folded down into the drain hole to allow water and moist air to enter the pipes.Water may leak between the drain and liner if you cut the hole completely.

Step 15: The top part of the drain needs to be screwed onto the bottom part.

The upper part of the drain has bolts that attach it to the bottom.The top and bottom of the drain hole are 1–2 inches above each other.To secure it, tighten the bolts on the bottom part.Since you need to add another layer of mortar, don’t screw the top flange into the drain until it’s flushed.

Step 16: Put another layer of mortar on top of the shower liner.

Follow the same process when mixing more mortar.Slope the mortar toward the drain by applying a thick border around the edges.Water won’t drain easily if the mortar is smooth, so make it as smooth as possible.Smooth out any rough areas by checking the mortar’s slope frequently.If you want to finish your shower pan, leave the mortar to dry.If you are putting tile in a shower pan, be sure to leave enough space between the mortar and the top of the drain to allow the tile to drain cleanly.

Step 17: It’s a good idea to dry-fit the tiles in the shower pan.

Take one of the tiles that you want to use for the shower pan and put it next to the drain.To mark how it fits on the shower pan, trace around the tile with a pencil.If you need to cut the tiles, trace the tile down to see how many are needed.It looks like a cohesive space if you choose tiles that match other fixtures.Depending on the style of shower pan you use, the number of tiles you need depends on it.

Step 18: Dust can be cleaned by wiping the mortar with a wet cloth.

The tiles can’t adhere to the shower pan if you have dust on your mortar.Wet a cloth with water and wipe it clean.Once the shower pan is cleaned, use a lint-free rag to dry it off.Don’t put tiles on your mortar if it’s wet.

Step 19: There is a layer of thinset on the shower pan.

It doesn’t set while you’re working if you only use enough thinset for 1-2 tiles at a time.Scoop and spread the thinset with a trowel.There is an 8 in (0.32 cm) layer on the mortar if you smooth the thinset with the trowel.You can find tile thinset at your local hardware store.

Step 20: You can secure your tiles by pressing them into the thinset.

To make sure the tiles line up with the marks you drew, set them on thinset.If you push down on the tile, the bottom may not fully contact the glue, which could cause your tiles to lift up.Wait 1-2 minutes before wiping the thinset off.If you want the shower pan to look uniform, then use tile spacers.

Step 21: The tiles should be flushed with the drain.

The container it came in should be used to mix the grout.Spread the grout over the tiles with a flat trowel or rubber squeegee.The surface is flat if the water doesn’t get through the spaces between the tiles.Allow it to dry for at least an hour after you apply the grout.You can find tile grout at your local hardware store.
