Installation tips

Unless you're comfortable with plumbing projects and have someone to help with the lifting, you'll probably want to leave toilet installation to a plumber. Costs vary considerably by location and typically range from about $200 to $450.

Here are some issues to consider before anyone picks up a wrench:

Look for the proper credentials

As with all pros, the plumber you choose should have proper licensing. Membership in professional organizations and several years of experience are a plus.

Check for liability insurance

Ask to see a copy of the certificate of insurance and check with the insurer to make sure the policy is in force.

Position the toilet first

If you're changing the toilet's location, decide where the new one will go before you relocate the other fixtures. Toilets require a 3- to 4-inch drain pipe. Relocating it may be more difficult than relocating and installing the smaller drains for showers and sinks.

Upgrade the lines

Have the plumber replace rigid chrome-plated copper water-supply lines with braided, flexible stainless steel. Besides easing future repairs, these lines help minimize leaks that may develop with minor movement.

Check for leaks

See that there are no leaks at the water-shutoff valve that connects to the wall or at the base of the toilet before the pro packs up and leaves.
