How difficult is it to change to a mixer tap?

I have two sets of taps in my bathroom (sink & bathtub) and would like to replace both of them with new mixer taps – for easier use and due to the taps’ age and wearing.
I would to prefer to install these myself if possible, as I’ve had some experience with tap installation in the past.
Are there any major changes that I will need to take into account beyond the piping of the hot and cold water to the single tap?
Anyone with any experiences of installing mixer taps would be appreciated.

"It’s a pretty simple process to change both. However, you need to take into account that your sink doesn’t already have a mixer tap I’m assuming it has a separate hot and cold. Which would mean your have to change the sink to one with just the single central hole for a mixer tap.

But for the bath you can buy a mixer tap that will fit your needs. Normally without good access room and space behind the bath. It can be a struggle removing and installing. I would suggest you buy a pair of flexible tap connector to make the installation easier.

"Hi,

make sure you turn the water off and open all other taps to drain water. New taps these days come with flexi which require you fit to a half inch threaded male fitting ideally a service valve."

"Ok this can be a reasonably easy job, but many times can be a real issue due to taps being fitted a long time they corrode, lime, rust and sometimes gather creating a problem of being able to loosen the nuts of holding the tap. You often need an extra pair of hands to hold the tape whilst under the bath or basin. Also make sure the taps you buy are suitable for your plumbing system low pressure or high pressure, if in doubt ask a professional"

"Hi,
As with all plumbing it can go very smoothly or be a nightmare. The one major thing to be careful of are the tap connectors, they ideally need to be replaced especially if the thread on new taps is shorter/longer."
