The best way to do it to use ditra and ceramic tile. We normally use ceramic tile as baseboard as well in the bathroom.

It depends on the material you going to use I can send you the best one if you like

It would be useful to know what materials from the cement floor base up to the walk on tile floor and how it should be waterproofed from the top and from the bottom so it lasts forever or until I move from my forever house.

I agree. DITRA and tile is a great waterproof solution. I would like to know more about what would be below the subfloor (Joists or cement?).

I totally agree with the above comments. Also, if the floor is concrete, is it level? if not, that is your first issue to correct. Then use ditra or something similar, or the panels (OSB with ditra attached) for warmth and level. After that the choice is open. Depending on your budget, tile, vinyl, lino and all options. Good luck.

There is more than one way to achieve a water proof subfloor in a basement bathroom.

One way is to install dricore or barricade subfloor panels making sure they are secured to the floor with a figure 5 screw/anchor pattern.

Next apply Ditra over top of the panels and make sure to tape the joints with schluter Kerdi band and return up the wall To make a complete water proof floor.

Install your tile on the floor and either use tiles a baseboards or a vinyl pvc baseboard

I dont understand why everyone try to do the easy way out . Ceramic tile in a basement will be cold and not so nice to walk on . The customer asked for a solution but no one asked if the area is being used for a rec room or as a finished basement which is used daily.

The type of subfloor I like to suggest to any of my customers is. By Strapping the floor with 1x3 that a treated. I usually take red tuck tape and cover the bottom of the strapping which almost covers 65% of the strapping then after strapping I lay blue foamback INSULATION between the strapping which is level with the strapping . Then 5/8 plywood . This type of subfloor will solve all issues of water and also be much better in the cold and your able to put any type of flooring you wish down.

And over all much cheaper then drycore

I agree with the previous idea. I did a basement very similar, rigid 4x8 foam board, 5/8 plywood drill threw into concrete, then engineered planking.

Keeps warm on the feet.
