Changing toilet. You shut off the valve on the inlet pipe then flush the toilet. Now sponge the remaining water out of tank and bowl. Get an old towel to put under back of toilet and remove inlet pipe from both ends. Now unscrew the 2 (or sometimes 4) holding bolts on the base and the lift toilet off the floor. I always have an old cardboard box or similar to sit it on, as the wax seal will make a floor sticky. Remove the toilet from the room to make space for the new one. Fit a new wax seal to the flange on the floor and fit new mounting bolts if necessary. Now re-fit the new toilet onto the bolts and wax seal. Gently rock it to settle the seal down, then fit nuts on and tighten it down. I always fit a new SS braided supply tube rather than the grey plastic junk, this needs no sealant or tape, just tighten the bolts . This is NOT a difficult job, you don't need ANY special knowledge, just common sense.
I would say about $600 to install a toilet. :d
I do that often, average cost is cost of the toilet, floor seal, connector, and one hour labour. (in my case $50 -Most plumbers are much more -)
The labor cost to install a float valve in the toilet will depend on the hourly wage of the plumber. The part should take no longer than a hour to replace.
The cost to replace just the toilet flange is around $5. The tricky part is knowing how to install it. If you use an outside source the cost will go up accordingly.
To install a wall-mounted toilet, first locate the wall studs and mark the toilet's height on the wall. Install a carrier frame for support, connect the water supply, and secure the toilet to the frame. Finally, seal the toilet to the wall and floor.
Replacing a toilet can be easily done by a non-professional. However, if you do have doubts I would suggest using a professional since installation is unlikely to cost a lot of money.
You can install the vanity first. Then, install the tile up to the vanity and around the pipe for the toilet. Then, install the toilet. That way, you do not have to replace the tile should you ever have to replace the toilet.
Yes, you would indeed need a permit to install another toilet. They are easy to get.
The time it takes to assemble and install a new toilet is about one hour.
No, toilet seats are not hard to install. There are two bolts that go through the rear of the opening on the toilet and when these bolts are secured, the seat is installed.
To install a new toilet flapper in a toilet tank, first turn off the water supply to the toilet. Flush the toilet to empty the tank. Remove the old flapper by disconnecting it from the flush valve. Install the new flapper by attaching it to the flush valve. Turn the water supply back on and test the new flapper by flushing the toilet.
When you purchase a new toilet seat, it is going to come with the instruction manual as to how to install the seat, when you get it in your home for installation.
