Gap between tile and tub?

  • by

If you have a gap between your tile and tub, it’s important to seal it properly. Otherwise, water can get into the space and cause damage to your tile or grout.

There should be a small gap (approximately 1/8″ to 3/16″) between the tile and the tub to allow for expansion and contraction.

How do you fix a large gap between a bathtub and floor?

If you have a 3/4 inch gap you’re going to be able to fill it with a piece of wood. Anything larger, you may need to use a different method.

It’s important to leave a small gap between the tub and the tile to allow for expansion. This will prevent the tile from cracking. A 1/16″ gap is ideal. This will also allow the caulk to properly fill the space and waterproof the transition between the tile and the tub or shower.

Should you caulk between tub and wall tile

If you are looking to waterproof and seal the area between your tub and tile, caulk is the best option. Caulk is flexible, waterproof, and non-porous, making it ideal for this type of application. Using caulk here will also make it easier to remove and replace when necessary and minimize the risk of damage to both tub and tile.

The thickness of the grout lines is determined by the type of tile you are using. For wall tiles, the common practice is to use 2-3mm grout lines. For floor tiles, the common practice is to use 3-5mm grout lines. The key difference in tile type, in relation to grout lines, is whether you tile is rectified or not.

What do you put between tub and tile?

Caulk is the best material to use when joining two different materials together, such as floor tile and a tub. This is because grout is not flexible and caulk allows for movement and provides a better sealant.

You’re going to cut it at about a 45 degree angle.

Is it better to caulk or grout around tub?

Caulk is a good material to use for filling spaces between tiles and walls in a shower or tub. It is flexible and can conform to the shape of the joint, which will help it stay in place and prevent water from seeping through.

The backer board is the supportive layer between your tile and the wall. It is important that the backer board overlap the tub flange so the tile has a stable backing. This may require shimming the backer board out from the studs so the wall is plumb. There should be a 1/4″ gap between the tub ledge and the backer board to allow for expansion.

How do you finish tub tile edges

Caulking is the cheapest and easiest method for finishing tile edges. Caulk provides a waterproof seal and is recommended for tiles with edges that already have a finished appearance, such as mosaics, tumbled stone, glass and some porcelain tiles. Install and grout all the tile, including the edge pieces.

If you’re not sure which type of caulking to use, silicone or latex, it’s best to use both. Silicone adheres best to slick, nonporous surfaces, while latex is better for uneven, porous, or mismatched surfaces. This way you’ll get the best possible seal and adhesion.

Why not use caulk instead of grout?

Caulk is a type of sealant that is used to fill in cracks and gaps. It is made of a flexible material that can be used on a variety of surfaces, including glass and tile. While caulk is strong and durable, it can shrink or dry out over time, so it is not recommended for large installations or as a replacement for grout.

If you are looking to avoid stains and mildew in your tile shower, it is best to use silicone caulk instead of grout. Silicone caulk is waterproof and more resistant to staining than grout. You can easily wipe it clean with a damp rag if it gets dirty.

How much expansion gap do I need for tile

There should always be a small space (1/4 inch or more, but never less than 1/8 inch) between the floor and the wall to allow for expansion and contraction. You can use a cove base or a manufacturer’s pre-made movement joint to create this space – both work well if installed properly. ANSI specifications require a movement accommodation joint whenever there is a change in plane, such as from the floor to the wall.

The fall is the measure of how much water the shower will drain in a given amount of time. The recommended ratio of fall within showers is between 1:60 and 1:80. This means that for every 60 seconds, the shower should drain at least 1 gallon of water.

What is the widest gap you can grout?

Cementitious grout is a mixture of Portland cement and water, with or without sand. It is used to fill in joints between tiles or bricks. The joints can be either small or large, but the size of the joint will dictate the type of grout to use. Smaller joints should be filled with unsanded grout, while larger joints should be filled with sanded grout. Heavier sanded grouts should be used for joints that are larger than 3/8″.

Now I’ve applied two layers of standard masking tape around the top of the shower tray And also the vertical gaps between the tiles. I’ve also applied a layer of waterproof sealant to the tapes surface.


A gap between a tile and a tub can be filled with either grout or caulk.

The gap between the tile and the tub is an important design element in any bathroom. It allows for expansion and contraction of the materials, as well as providing a drainage space for water. The size and shape of the gap should be considered carefully to ensure that it is both functional and aesthetically pleasing.
