How to Replace Your Bathroom Floor

By Peter Ackerson

Replacing a ceramic tile bathroom floor can be done by the average skilled homeowner. You will need a couple of specialty tools but none are really expensive and the tools will last forever. Realize that the bathroom will be out of commission for about a week or so and plan on it. If you are dong this replacement work part time or nights or weekends add some more time. Remove all loose items from the bathroom. Next remove the toilet. Floor covers at pipe penetrations (escutcheons) should be removed as well. If the existing floor finish is ceramic tile over wood, striking the tile with a large hammer will generally dislodge most of the tile. The rest can be removed using a sharp cold chisel or a masons chisel and hammer. You must achieve a smooth clean sub-surface when you are done. Wear safety glasses at all times.

Once the old tiles are removed you must plan the layout of the new tile patterns. Using the actual tiles, dry lay them on the floor to not only set the pattern but to check the cuts that will be required. It s important to not end up with a sliver of tile against one wall and an almost full tile on the opposite side. You want to get, as close as possible, to have two equal pieces on both sides of the room. Once you have the layout where you want it make sure the rows are parallel to one wall. The wall that is to the right of the doorway is the most commonly used wall as it is where you see the floor tile first. If those rows are straight the rest of the room will follow.

Measure off the wall two feet or to the center of the doorway. If there is no pattern in the tile, center a row in the doorway for best appearance. If you are making a pattern, the pattern may look it's best if centered on the room itself. It is your preference so just decide before you start to lay the tile. Using your chalk line, strike a line across the room as a reference starting point.

You will need a ceramic tile cutting tool, nipping pliers and perhaps a good pair of tile notching pliers as well. The cutting tool can be purchased and is not very expensive. If you foresee a great deal of cutting is required, rent a tile wet saw for a few days. It makes the work a good deal easier. Starting at your chalk line, lay your first rows of tile to one side of the line and do not cover the line as you work. The line will be your grout joint. Work you way around the room doing all your cut tiles as you go. You will not be able to get back to these areas until after the adhesive sets in a day or two. Again, cut all the tile as you go. Wipe off any excess adhesive that squeezes up between the tiles or gets on the faces. You want the spaces between the tiles to be as clean as possible to allow grout to be pressed down into the joints later.

Here's your biggest and most important point. Do not for any reason try to walk or crawl back over the tile once it is laid. No matter how careful you are, you will twist the tiles out of alignment with the only fix being total removal. If the room has a locking door, lock it. If not, barricade the doorway with whatever you can to prevent anyone from accidentally walking on your fresh tile work. Twenty four hours is a minimum drying time. Keeping foot traffic off the floor until the grout is installed is also important to prevent any debris or dirt from their shoes from getting into the grout joint spaces.

Once the tile adhesive is dry you may proceed with the grout installation. Grout should also dry twenty four hours before foot traffic is allowed to return. If there is to be additional construction work in the room, place some good quality brown craft paper over the tile to protect the finishes. If not, replace the toilet and other room decorations.
