I am going to attempt replacing the toilet unit in my house in Chiang mai .We bought a new one ,which is all one unit (flush bowl connected to pan ) .Will i need a wax ring (it drains out the floor not to the wall ) .If so are wax rings available here ? I live near a Homepro ,and several Thai hardware shops.
Another Q.if i have to drill new bolt holes through the tiles ,for anchor bolts ,is there a special drill bit for tiles that i should use ?
