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.
Installing a toilet is actually quite easy, and you can do it yourself (or with the help of a friend).
You will only need a few basic tools, and a new wax ring.
Turn off the water and flush the old toilet (to get most of the water out of it). Disconnect the water inlet, and remove the two nuts at the base. Lift the old toilet straight up; it may be "sticky" because of the old wax ring. A little twist left and right will help.
I usually set it in the bathtub, because there will still be some water in it.
Clean off the old wax ring from the pipe; it needs to be good and clean. put the new wax ring down, and set the new toilet squarely on the new wax ring. It's important not to wiggle it around and so forth at this point, because if you mess up the wax ring, you'll be doing this over again.
Put the nuts back on the stand bolts, and bolt the new toilet down. Don't over-tighten the nuts; just make them snug, or you take a chance of cracking the porcelain, breaking the bolt, or worst-case, breaking the collar (then you will have to get a plumber... replacing collars is not a beginner task).
Once the base is down, follow the directions for the tank, valve, float, etc. Reconnect the water supply and turn it on. The tank should fill. Check for leaks while it is filling; there should be no drips. Leave the top of the tank off so that you can adjust the water level if necessary to the "Fill" line in the tank. Flush and watch for leaks; especially where the tank meets the bowl, and around the bottom of the bowl (leaking from the wax ring).
That's pretty much it.... you may have to make minor adjustments to the chain (if your system uses one), to the fill level, and so forth, but that's really all there is to changing a toilet. I've changed dozens of them.
Answer:
Consider some of the other aspects of the do-it-yourself route. As much as saving a couple of hundred dollars on plumber's fees is a good thing and the process is relatively simple (see above) there are some drawbacks:
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.
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.
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.
It's less than 1 hour labour in most cases. -That's what I'd expect to pay.
