Tiling on 45x45 studs?

[Earplugged]

I was thinking of putting up tiles in the guest toilet and noticed when I started tearing down the drywall that two of the walls are framed with 45x45 cc600. Can it become stable enough if I put a layer of plywood under the drywall and then tiles 200x500, or is this doomed to fail? The walls are 150cm and 180cm, so they are relatively short walls, which should increase the chance of it becoming more stable? (Only a toilet, so no waterproofing to consider on the walls)

should work if you offset the seam

Embed additional studs so you get 30 cc. Use 15 mm wet room plyfa under the drywall, so you have good material to screw into as well.

If I lay down 15mm våtrumsplyfa, it will cover the entire way and there will be no joint at all on the width, should be the most stable option?

Yes, a board to screw into should definitely go there; plain drywall is so boring... there is a cabinet attached to the wall today, so some type of reinforcement must be behind it, I presume (haven't torn it down there yet).

If I lay down 15mm wet room plywood, it will reach all the way with no seams at all across the width, should be the sturdiest option?

If you space 30 cc and use 15 mm wet room plywood, it will hold for a cabinet. Unless it's a real piece you're planning. Then you should reinforce with studs behind. Otherwise, 15 mm plywood is considered one big reinforcement.
