My bathroom (approximately 5'x5') has old linoleum tile (in 12" squares) that are coming loose. I would like to install ceramic tile but don't know where to start. The walls have ceramic tile, but there is a small gap (about 1-2") on one wall where it meets the floor. When I redo the floor I would like to repair the gap.

What should I do first?

 

You're gonna have fun. Laying a new tile floor is not difficult. I suggest a DIY book on tiling to get started. You'll need a few basic tools: tile cutter, trowel, grout sponge, etc... which won't set you back much.

For now.. leave the floor "as is". Get your book, pick out your tile, thinset, and grout. At this stage you can decide whether or not to replace the wall tile (you'll probably want to for matching purposes).

In a nutshell:::: When you're all set, you'll take up your current floor - a good scraper will prove invaluable... and also remove with as much care as possible, the wall tile to be thrown away or repositioned if you like them. From there you'll lay out your floor pattern (small room should be simple) and mark/cut the tile needing to be cut. Mix and spread your thinset and apply with grooved trowel. Lay your tile, using plastic spacers for even rows/grout lines. Let dry 24 - 48 hours. Remove the plastic spacers. Mix and spread your grout..... using the grout sponge/squeegee to press it into the joints. Wipe the excess thoroughly after 15 - 20 minutes and work your joints to your liking. About 4 hours later you will use a clean dry rag to wipe the light grout film off the tile.... The next day - you'll have a new floor!

Please recognize that the above is a very simplified version of the process.. I cannot stress getting technical assistance from an experienced friend - or as I mentioned - a good book. There are lots of them on the market and are very easy to follow.

Good luck....
