Tile under the shower base?

Separated from Installing Shower Base over existing tile floor

Preparing to install an American Standard neo angle shower base and feeling like installing the tile fully across the floor then setting the base on top of it will give the best finished look as well as the most durable result. If water gets past the caulk it will be on top of tile.

The idea of doing the whole floor and then putting stuff on top is how they build trailers/mobile homes. It's a quick and inexpensive way to work but it causes headaches down the road when you try to perform repairs or remodel.

Where does the water go once it's on top of the tile? Since you will caulk the edge of the shower where it meets the floor the water will only be able to go backwards into the wall where it is out of sight.

I would not tile the whole area. It creates a big problem for anyone in the future that wants to change the tile and I don't see how it will offer any protection from a leak.

Showers are not supposed to leak if installed properly. Where is the potential caulking you are concerned with letting water through? at the drain? along the sides? where the base meets the tile?

The shower base will look more finished if you tile up to it and hide the front lip behind 5/8"" of tile/cbu. A nice bead of flexible caulk to match the color of the floor tile will make it blend. Should the need to have repairs done in the future due to a leaky toilet or something, and you have to do floor work. You are dooming yourself to having to remove the shower as well as the floor tile to make the repairs. I can not think of one advantage to doing the tile as you are suggesting.
