Bathroom water damage is something that occurs frequently for many homeowners. In order to repair the water damage, there are several steps that you will need to follow. Here are the basics of how to repair bathroom water damage effectively.

Step 1--Shut Off the Water

Before embarking on a repair in the bathroom, you should make sure that the water is shut off to the room. Go to the main water valve and turn it off. This will prevent any further water damage during the process of the repair.

Step 2--Prepare the Room

Before you can repair any water damage, you will need to prepare the room for the job. You will need to remove the toilet by unscrewing the bolts that hold it to the floor and disconnecting the water line. Take the toilet out of the room and leave it in an area that is out of the way. If the water damage went under the cabinets, you will need to take the cabinets out of the room as well. In most cases, ceramic tile will not be damaged by water. However, if there was significant water in the room tile will be damaged as well as any vinyl products. You will need to remove the damaged flooring and take it out of the room. If you have ceramic tile, you will need to chisel about with a hammer. If you have vinyl, you should be able to scrape it out with a large scraper blade.

Step 3--Repair the Sub Floor

If you have a wood subfloor, you will most likely need to install new plywood. Cut out the damaged areas in the existing wood subfloor. Then place new plywood on the floor and nail it in place. If you have a concrete subfloor, you may have to apply self-leveling compound in order to level out the floor. Make sure that the concrete surface is dry before doing anything else.

Step 4--Repair the Drywall

If there is any damage to the drywall around the bottom of the floor, you will need to repair it. Put some new drywall in place and attach it with drywall clips. Apply some tape to the joint and then put joint compound over the top. You can then repaint the drywall.

Step 5--Install New Flooring

Once the subfloor is repaired, you can begin to install the new flooring. If you have ceramic tile to install, you will need to install concrete board before laying the tile. Then apply the tile to the top of the concrete board using thinset and a trowel. Allow a day for the thinset to dry and then apply grout to the joints. If you have vinyl, you will spread out the adhesive with a trowel and then press the vinyl down into it.

Step 6--Finishing Up

Once the flooring is repaired, you can reinstall the cabinets and the toilet. At that point, your bathroom should be ready to use again and you can turn the water back on
