Raising the floor of the bathroom

Raising the bathroom floor is an effective way to adjust the height of the toilet flange. Depending on the height you want to add, it’s best to pad the tiles underneath for proper support. To raise the floor, an extra layer of tiles is sufficient, or, for example, risers can be used. B. Plywood, to be installed prior to laying the tiles. This allows the toilet to be placed correctly on the bumper. You can also use cement slabs to raise the height of the toilet. In the following paragraphs, we will explain how to raise your bathroom floor using the ideas above:

Method 1: Plywood for floor extension

Step 1:You will need a circular saw for this task. Cut the plywood according to the amount you will use. Measure the area of the floor to be cut to the correct size. Step 2:Now measure the distance from the center of the toilet flange to the nearest wall. Draw this size on the first piece of plywood with a pencil. The next measurement should be the distance from the opposite wall to the toilet flange and its center. Record this measurement on a second piece of plywood. Step 3:After you have measured the distances, add a half inch and draw a circle with a compass or round head. The circle can then be cut out with a wood carver. Step 4:Now it’s time to mount each veneer on the toilet flange and make sure it fits properly. Secure the plywood with glue or screws. You are now ready to install the toilet.

Method 2: Cement slab

If the space between the bathroom floor and the outer circumference of the flange is minimal, it can be filled with a cement slab, on which tiles are laid. The advantage of using cement slabs is that swelling due to water leakage is impossible and it is a stable flange solution. Swelling can lead to cracks in your tiles and cost you money to replace them. You can avoid this inconvenience by raising your floor with a cement slab. Follow the steps below to learn how to do this: StepMeasure the ground where you want to raise the subfloor. This will determine how many pieces of cement board you will need. Step 2:Measure the radius of the flange to create a round shape on the back planks. You will need a pencil to draw a circle before making the hole. Step 3:Put 4 pieces of cement board together to form a larger square. Draw a circle in the center of the largest square and add a half inch to the measurement. Now cut out a circle and make sure the plate fits perfectly on the toilet flange. Step 4:Spread the cement evenly over the entire raised floor. Then lay the tiles while the cement is still wet. Secure the rear panels with corrosion resistant screws. Make sure cement is applied around the outer flange and between the screens. Step 5: Finally, to install the tiles on the subfloor, apply tile adhesive to the tiles, making sure the tiles cover the joints well. You can then screw the flange to the floor and continue with the installation of the toilet.

Use of mortar

Joint sealant is another excellent material to use when the toilet flange is too high. Follow the steps below to use this tool: Step 1: Start mixing the coulis. Follow package directions or put a small amount in a container and add water at a ratio of 6 mortars to 1 water. This will ensure that you have enough grout to get the job done. Step 2:Remove the toilet bowl and place it on the four rubber bumpers. The washers are used to prevent the toilet from moving around the flange during grouting. Step 3:Now take the mixed mortar and fill the space with it. Do it all around the perimeter of the toilet. Wait 24 hours for the grout to dry. Step 4:Once the grout is completely dry, remove the rubber seals. It can be difficult to get them out, but with a little effort they will come out. Step 5:After you have removed all joints, seal all areas where you have removed the joints. Step 6:Finally, tighten the screws on the bottom of the toilet bowl so that it is secure. Tip: While the grout is drying, you can speed up the drying process by spraying water on the grout. Use a spray bottle and add as much liquid as you can. This will make the mixture firmer when it hardens. Have you tried all the methods above and still not satisfied with the height of the bridle?
