Question ceramic tile floor too high

We're renovating our house and all of the upstairs floor is floorboards in pretty good condition. We want to lay a ceramic tile floor in the bathroom, and have read that you need at least an inch and a quarter of hardboard/concrete under the tiles. If we do this, the bathroom floor will be about an inch and a half higher than the landing (carpet). Is there anything we can do to get around this? Please help!

If the subfloor is in good shape, I can't see why a layer of half inch plywood and a quarter inch backer board wouldn't work just fine. To be honest, if it were my house I would be comfortable just useing half inch "hardi" backerboard over the subfloor and tiling it. As a professional I shouldn't say that though. The plywood/backerboard will only net about one inch with tile.
Good luck

Thanks Bryan

I think we will risk it. Some friends of my sister used half inch plywood, and flexible adhesive and grout, and they said it worked fine.

I think we'll risk it!

I don't think you need an inch and a half of hardboard/ concrete.

What you need is a solid subfloor and a layer of cement board.

solid subfloor ususally is plywood nailed down to the joists,
and then a layer on top of that, nailed to the first layer. (not the joists).
with 2 - 3/4" plywood, that gives you your 1-1/2" suitable sturdy floor.

However, ceramic tileing on top of that is not recommended.
So you need a layer of hardboard screwed down on that.

Then you'll put down your tile with thinset,
and enjoy it for years to come.
