I had a bathroom completely refitted about 3 years ago. After the job was done, the flow at the taps, showerhead etc was significantly reduced. The guy who did the work told me that the old, wide fittings were no longer available. Of course, this was bull****. It takes an age to fill the bath and the shower is *just* adequate on full bore.

Is there any virtue in fitting a pump to the bathroom supply only?

I'm on gravity feed.

Well I've seen it done right enough, but whether it will work in your case
depends on where the bottleneck is I suppose.

Potentially, yes, but there are complications. Is the shower on a mixer
tap off the bath? If so you need to pump both hot and cold. But, when
you are putting hot only into the bath (or sink) then the cold water
pump is running with no flow, I don't know how well they cope with that.

I have a separate shower room with its own supply of hot and cold. I
have a single Stuart Turner in the loft that feeds the bathroom (and
kitchen) hot water. And a second double headed ST for the shower.

If you've got room for a pump in the base of the airing cupboard,

e.g https://www.screwfix.com/p/salamander/2502t

give it dedicated feed from cold tank in loft, and a dedicated feed from
the hot tank using a surrey/warix/essex/tech flange

If you han't got room at base of airing cupboard there are alternative
"negative head" pumps depending on location.

The shower's separate from the bath. It's really only the hot which is a problem. The hot to my en suite (which is on the same level) is fine.

But if you boost the pressure to the hot side, you need to do the same
to the cold side, or the shower will be difficult/impossible to control
temperature.

If the supply (indirect tank) wasn't affected I'd suggest taking a look

or you could troubleshoot the install. Would make more sense surely.

What fittings has he used? Is it copper all the way to the taps or have
flexi pipes with a bore of perhaps 10mm been used for the last part?
Any isolation/maintenance valves been fitted? If so are they full bore
and/or have they been fully opened.

I fitted one to the hot water supply to the shower/bath, and it's been
working very well for a few years now. Missus wanted a mixer tap/shower
thing, and I didn't know at the time that gravity feed would only push a
trickle of water through it (although I believe that there are
low-pressure mixers out there). Worse, the mains pressure can actually
push cold water backwards and up into the header tank.

So I fitted a pump to the hot water only (the cold mains supply has more
than enough pressure). I discovered that the problem of pushing water
backwards still exists (if you turn it to cold, open the tap, and move
it to the hot side) because the pump only works when its flow switch
detects hot water going through it in the normal direction. So I fitted
a flow switch (fortunately, the pump already has contacts for this
purpose) into the cold supply, so now the pump pumps (or attempts to)
the hot water even when only the cold water is flowing.

So, probably not a setup that anyone would recommend if doing it all
from scratch; but now I have something that works very well for me.

They cope ok IME... Even with a mixer shower you want want it running at
near cold or near hot - so only with significant flow on ones side.

The pumps are designed such that they can "slip" - i.e. they don't
hydraulic lock if you block off flow on one impeller.

I have a separate shower room with its own supply of hot and cold. I
have a single Stuart Turner in the loft that feeds the bathroom (and
kitchen) hot water. And a second double headed ST for the shower.

I have done a 2.2 bar ST dual pump feeding a bath and separate shower.
It worked for both shower and bath.

And he has fitted continental taps which are designed for direct
mains connection. He knew this would be a problem.

you'll need a pump that drives cold and hot feeds from the airing
cupboard, probably fitted in the airing cupbaord.

Then send the bill to the first bloke. If he procrastinates,
just go after him in the small claims court, doesn't cost much.

We recently had a new bathroom fitted (my days of such major jobs are
behind me).

Part of the refit was an Aqualisa Shower. It has a pump which can go in
the loft, under the bath, ...... Our has a gizmo to divert the output to
a 'rain head' or one of those hose head things. The bit in the shower
is just a switch, there is a cable to the pump/control box which has hot
and cold 'low pressure' feeds from the respective tanks. The output is,
in my view, all you could want but not variable for pressure- just temp.

We are delighted with it, so much so the plan is to have another one
fitted in our ensuite which currently has an Electric 'instant' mains
pressure shower.

Our refit was complicated by the fact the bathroom had mains pressure
cold water and gravity hot. The fitter ran pipes for the new shower-
quite a run due to the layout of the house.

Blaming the fittings seems a bit odd. I can't see how, all other things
being equal, the supply is that much lower. Does the toilet fill at
roughly the same rate?

If the supply (indirect tank) wasn't affected I'd suggest taking a look
at the isolation valves. Might be they weren't turned 'on' fully.

Or reduced bore isolation valves were used instead of full-bore.

or 15mm pipe for the low pressure hot, instead of 22mm?

That suggests an obstruction or a kink in the pipe. Is the pipe 22mm or
15mm?

I also suggest you measure flow rates with both the en suite and
bathroom. ie how long to fill a 5gal bucket or a container of a known size.

None of these problems should have happened.
