I want to rip up the old linoleum in my bathroom and install some tile. The previous owners laid the current layer of linoleum on top of the original linoleum. From the little bit I’ve peeled up to look underneath it looks like chip board underneath that. Does that mean I need to lay some kind of backerboard underneath the tile? I also plan on tearing out the curent cabinets and installing new ones. Should I install the tile or the cabinets first?

Ceramic Tile Backerboards

There are many types of backerboard products suitable for use with ceramic tile. We will focus on two of the more popular products: 1/2″ thick, water resistant greenboard sheetrock and cementitious type ceramic tile backerboards (recommended).

Subfloors

We recommend that 1/4″ or 1/2″ thick cementitious ceramic tile backerboards be installed as an underlayment over wood subfloors. The exterior grade plywood should be at least 1-1/8″ thick (5/8″ minimum) in order to provide for a structurally solid, movement free foundation. In addition, the space between the joists should not exceed 16″ on center. In any case, the maximum allowable concentrated deflection of your subfloor may not exceed L/360 of the span.

Install backerboard using a non-modified thinset mortar and 1-1/4″ screws or nails.
