Does shower pan go in before backer board?

It is important to install the shower pan before the backer board. The shower pan should serve as the base of the shower, providing a waterproof flooring before placing the backer board. If the pan is not installed correctly, the backer board may be subject to water damage or mold if it is not properly sealed.

The pan should be securely attached to the drain and waterproofed before the backer board is installed. The pan also provides structural support for the backer board and should be level before backer board is installed.

Using a level, mark reference lines around the shower that will serve as guides when placing the backer board. Make sure to fill in any depressions with the thinset. Finally, cut the backer board to the necessary size, waterproof it with a liquid membrane, and then screw the board into the studs.

What goes first shower base or wall?

When it comes to installing a shower, the specific order of installation will vary based on the type of shower. However, generally speaking, the base should go first when installing a shower. This is because the walls – typically made of tile – are supported by the base, which will ensure a level and secure foundation.

This will also ensure that the walls are properly sealed, so that water doesn’t leak and cause damage to the area. Additionally, it’s important to make sure that the base is level and that the walls are appropriately reinforced before adding finishes such as tile, grout, and silicone caulk.

Following these steps will ensure that the shower is properly installed and will provide a long-lasting and safe fixture.

What goes behind backer board in shower?

When installing a shower, it is important to use backer board behind the tile. Backer board helps protect the subfloor and walls, prevents water damage, and helps tiles stay in place. The most common type of backer board is a cementitious board like “WonderBoard” or “Hardiebacker.


These boards should be securely installed using either cement board screws or galvanized nails. Cement board screws are the better choice as they provide a better grip than nails. It is important to ensure there is an even gap of 1/8 inch between the boards, and all seams should be sealed with fiberglass tape.

This prevents water from getting behind the boards and into the wall cavities.

Once the backer board is installed, it should be covered with a liquid waterproofing membrane. This membrane helps keep water from seeping through the tiles and into the wall cavities, potentially damaging the walls and subfloor.

The membrane should be applied evenly and completely for maximum protection. After the membrane is applied and cured, tile or another type of waterproofing material can be installed.

Should cement board overlap the shower pan?

Yes, cement board should overlap the shower pan. Cement board is the recommended substrate for tile and stone installations and is an important component in creating a water-resistant layer for a shower or tub surround.

Cement board, when installed according to industry standards, should overlap the shower pan’s edge and extend at least an inch onto the wall studs or blocking. This overlap is critical because it prevents water from entering the pan and seeping behind the board and tile substrate or damaging wall components.

Additionally, the overlapping of cement board helps to secure the cement board to the existing substrate and in turn, prevents movement or shifting during periods of heavy moisture or use.

Does shower pan sit on subfloor?

Yes, shower pans should always sit on a subfloor. The subfloor should be structurally sound, properly leveled, and sealed against moisture. Depending on the type of shower base being installed, the subfloor may need additional preparations.

For example, if a poured, tile-ready shower pan is being used, it requires a damp-proofing membrane and a mortar bed for installation. If a direct-to-stud shower surround is used, then the subfloor should be level and smooth, but it may not require the addition of a membrane.

It is best to check with the manufacturer of the shower base to get specific installation instructions before beginning work.

Should shower tray be fit before or after tiling floor?

Whether you fit the shower tray before or after you tile the floor is really a matter of personal preference. If you fit the shower tray first you won’t have to worry about the tiles being damaged or broken when you install it, but you won’t be able to see how the tiles will look in the shower space.

If you tile first, then you can plan how you want the tiles to fit around the shower tray and create a neat, uniform look. However you may need to cut the tiles around the shower tray and there is also a risk that you might damage the tiles when installing the shower tray.

Whatever you decide, make sure you have everything you need to fit the shower tray and that you have followed all the manufacturer’s instructions for installation. The most important points to remember are to use the correct sealant and grout, an even layer of adhesive, to leave a gap for expansion and to make sure the shower tray is level.

Can you lay a shower tray on backer board?

Yes, you can lay a shower tray on backer board. It is a good idea to ensure that your backer board is made from cementboard, as this is waterproof and will not degrade over time when exposed to moisture, as other board materials can.

You should also take extra caution to make sure the board is installed properly along the shower walls. For example, the edges should be sealed with silicone or other waterproofing material, and the screws should be set slightly into the mortar joint between the tile and the backing board.

Additionally, make sure you use waterproof screws, as this will further help make sure the tray is secure and properly sealed. Once the backer board is in place, setting the shower tray is relatively straightforward.

Make sure to use thinset mortar that has been waterproofed to secure the tray and to ensure that it is level and properly secured.

How do you install cement board around a shower pan?

Installing cement board around a shower pan is a fairly straightforward process, but it is important that it is done carefully and correctly in order to ensure that the shower pan is properly sealed.

The steps for installing a cement board around a shower pan are as follows:

1) First, make sure that the area around the shower pan is clear of any debris and is level and flat.

2) Cut pieces of cement board to fit around the shower pan. Use a masonry saw to make precise measurements and cuts. It is also important to use a wet saw to reduce the likelihood of breathing in dust particles.

3) If necessary, use mortar to adhere the cement board to the shower pan. Apply a thin layer of mortar along the edges of the shower pan, then press the cement board into the mortar in order to ensure a secure fit.

4) Next, use self-tapping cement board screws to secure the cement board to the shower pan.

5) After all the cement board has been installed, use a good quality caulk to fill any gaps or cracks between the shower pan and the cement board. This will help make sure that the shower pan is waterproof.

6) Finally, use a grout trowel to spread grout over the entire cement board surface. This will create a seal between the cement board and the shower pan, which will help protect the shower pan from leaks and water damage.

Once these steps have been completed, the cement board should be properly installed around the shower pan and the shower pan should be adequately sealed.

How do you install a mortar shower pan before putting membrane in?

Installing a mortar shower pan before putting membrane in requires taking several steps in order to ensure a secure and waterproof seal. Begin by preparing the surface of the shower pan location. Make sure it is clean, level, smooth, and dry.

Next, construct your mortar bed by mixing together two parts of sand, portland cement, and lime in whatever ratio is recommended for your chosen mortar product. Spread out half of the mixed mortar over the shower pan location using a trowel.

Take the pre-formed shower pan and apply a layer of mortar to the underside. Place the pan firmly into the mortar bed, adjusting it as needed. Slope the pan toward the drain in order to provide optimal drainage.

Fasten the pan to the shower walls using thinset mortar, and fill any remaining gaps with additional mortar. Embed the drain into the mortar, screwing it in to tightly secure it. Add the remainder of the mortar to the top of the shower pan and let it fully cure before applying the pre-sloped membrane.

The pre-sloped membrane helps ensure proper drainage and will provide an additional layer of waterproof protection. Once the membrane is in place, you are ready to proceed with the rest of the shower installation.

How much space should be between shower pan and backer board?

When installing the shower pan, it is important to leave a sufficient amount of space between the shower pan and the backer board. This space should be approximately 1/4 to 1/2 inch, although this may vary depending on the type of backer board being used.

Additionally, it is important to make sure that the space is completely filled with a waterproof mortar or silicone caulk, in order to avoid water damage. It is also important to ensure the area between the pan and the backer board is properly sealed, in order to prevent any moisture or water from getting into the walls or flooring.

Lastly, it is also important to make sure there are no gaps or spaces between the pan and the backer board, in order to prevent any water from leaking through.

What’s the thing to bed a shower tray on?

The thing to bed a shower tray on is a shower base and/or mortar bed. A mortar bed is a blend of cement, sand and water which is used to evenly spread pressure underneath the shower tray and create a waterproof base.

This is a necessary step in installing a new shower tray as the mortar will provide a solid foundation and ensure the shower tray will last for many years of use. Once the mortar bed is set and cured, the shower tray can then be installed on top.

Additionally, if you are adding a shower tray to an existing shower base, it should be seated with a waterproof adhesive to ensure a secure fit.

What do you put under a shower base?

Underneath a shower base, there are several components that need to be installed in order for the base to function properly. These components usually include a shower drain, a shower pan liner, a waterproof membrane, and a shower drain assembly.

The shower drain is the outlet from the shower base, which allows water to flow down the drainpipe and out to the sewer or septic system. The shower pan liner is placed directly inside the shower base, creating an impermeable barrier to keep water from leaking out.

A waterproof membrane is then placed on top of the liner to ensure that no water can escape from the shower. Finally, a shower drain assembly usually a combination of drain grate, strainer, and tailpiece is installed to provide an easy draining path for the shower water.

It’s important to be sure that all components are installed properly and that they meet local building codes in order to ensure the safety and proper functioning of the shower base.

Do you need to put anything under a shower pan?

Yes, it is important to put something under a shower pan. The purpose of this is to create a waterproof barrier between the floor and the shower pan. This barrier will help stop moisture and water from seeping into the rest of the house.

Common materials used under a shower pan include waterproofing membrane and a pre-formed sloped shower pan liner. When installing a waterproofing membrane, it is important to ensure that the membrane is installed in a seamless way and that all seams are overlapped and sealed with a waterproofing sealant.

The pre-formed shower pan liner should be installed on top of the waterproofing membrane and covered with mortar mix to create a watertight seal and protect the shower pan from damage. Additionally, tile may need to be placed on top of the mortar to create the finished shower floor.

Does a shower pan go under tile?

Yes, a shower pan goes under tile when installing a tile shower. The shower pan provides a waterproof barrier beneath the tile and is an important component of a tile shower installation. The shower pan should be installed according to instructions and any local building codes.

The shower pan liner should overlap the wall liner material and extend up onto the walls a few inches. The shower pan should also have a slight slope, or “pitch”, that directs water towards the drain.

If the shower pan is not sloped properly it can result in water pooling in the shower and eventually lead to water damage. After the shower pan is installed, the tile can be installed over it. Thinset mortar can be used to adhere the tiles to the shower pan.

After the tiles are installed, a caulk or grout can fill any gaps between tiles to ensure water resistance. A sealant can also be applied to the shower pan liner and tile to protect the waterproof barrier and provide additional protection.

Which shower wall to tile first?

When tiling a shower, the best approach is to start with the wall that sits directly behind the shower head first and then work your way around. If you’re using tiles with a pattern and need to repeat the design, start with the bottom and work your way up, so you can ensure a consistent pattern throughout the shower walls.

Next, lay out your tiles and mark the walls with a pencil as a guide. When tiling the walls, use a level to make sure each line of tiles is even. If necessary, use spacers to maintain the gaps between each tile.

Once the wall is completely covered with tiles, use a wet saw to cut any pieces that don’t fit properly. When the first wall is done, move onto the adjacent wall and repeat the same steps.

If you’re tiling a large shower, always make sure to be mindful of the weight of wet tiles and thinset. As long as you follow the proper steps and take your time, you should have no problem tiling a shower.
