Fixture installation, and the measurement to take before you buy anything

The most common problem with a new fixture is not the fitting of it. It is discovering on the day that the toilet does not line up with the drain, or the faucet does not match the holes in the sink. Each of those has one number behind it, and every one of them can be checked in about a minute with a tape measure.

Before you buy

Measure this first

Pick what you are replacing. These are the checks that stop a fixture going back to the store, and they are worth doing before you fall in love with something.

What to measure, and what usually goes wrong when nobody does.

What are you replacing

    Send us a photo with a tape measure in the frame and we will confirm it before you order. That takes us two minutes and saves you a return trip.

    Honest heads-up

    Why a simple fixture job sometimes grows

    This is the single most common reason a quick job turns into a longer one, and it is better said in advance than discovered with the water off.

    • Old shutoff valves often will not reseal. The small stops under sinks and behind toilets are frequently multi-turn valves that have sat untouched for decades. Closing one for the first time in twenty years can be the last thing it ever does properly, and then it weeps rather than shutting.
    • Which is not carelessness, it is age. The valve was already at the end of its life. Replacing a fixture is simply the moment it gets asked to work.
    • So we quote for the possibility rather than pretending it will not happen. If yours are old multi-turn stops, we will tell you upfront that replacing them is likely and what that adds, instead of raising it halfway through with your water off.
    • Quarter-turn ball stops are the upgrade worth taking. They seal reliably, they are quick to operate in an emergency, and they make the next job on that fixture a small one. It is a modest addition at the point where the pipe is already open.
    • Corroded supply lines get replaced, not reused. Braided stainless lines are inexpensive and they are a common source of sudden failure when they are old. Reusing one to save a few dollars is a poor trade.
    • Toilet flanges are the other one. A flange that sits below finished floor level, or one that has cracked, needs correcting before a new toilet goes on, otherwise the seal fails and you find out slowly through the ceiling below.
    Worth considering

    Fixtures that make a house easier to live in

    If a bathroom is being changed anyway, some of these cost very little extra at that moment and a great deal more as a separate job later.

    • Comfort height toilets. Taller than the traditional height, which makes a noticeable difference for anyone with knee or hip trouble. Same footprint, same rough-in, so it is purely a choice of which unit to buy.
    • Blocking behind the wall for grab bars. If a wall is open for any reason, adding solid backing costs almost nothing now. Fitting a properly anchored grab bar later, into a wall with nothing behind the tile, is a much bigger conversation.
    • Thermostatic or pressure balancing shower valves. These hold temperature steady when a toilet flushes or a washing machine fills, which is a comfort feature and a scald protection feature at the same time.
    • Lever handles rather than knobs. Easier for arthritic hands, and no more expensive. One of those choices that costs nothing to make correctly at the point of purchase.
    • A mixing valve at the water heater. Lets the tank store hotter while delivering safer water at the tap, which matters where there are young children or anyone with reduced sensation. Worth asking about alongside water heater work.
    • Shutoffs where there are none. Plenty of older fixtures have no local stop at all, so any future problem means shutting the whole house off. Adding one while we are there is small and it pays for itself the first time something goes wrong.
