How to change a shower bar valve. Shower mixer install & replace!

An hour after watching this I felt confident enough to buy the parts I needed. Half an hour after watching it for a second time, my new mixer bar was installed! Diolch yn fawr!!

Thanks for this video. I am not an experienced DIYer (can't find the start button on a hammer, for example), but watching this, I felt confident enough to have a crack at this myself. I can honestly say, that this only took 10 minutes, 5 of which was turning off the water supply. Thanks very much. I'll keep an eye out for other videos on any other DIY I need to do.

A perfect ‘how to’ video. No loud music playing over your voice when people are trying to listen to you. Clearly explained from start to finish. Well done!

This video saved me tons of money spent on plumber. Bless the plumbers. but I can change my own tap now! 🎉 Thank you!

Thank you! Was thinking about getting a plumber in to change ours, but watched your video and decided I could do it myself! My new shower mixer looks great and doesn’t leak. Thanks again

I just replaced my shower bar using this video: works perfectly! Thanks

Excellent video showing how simple this job is, not daunted about fitting my new one when it arrives today! Thank you 👍🏻👍🏻

Thanks so much for this video. About to replace two showers in a house that we’ve moved into. Thanks again!

I just replaced the shower bar with help thanks to this video. The flow knob on my old shower bar in the ensuite had worn after about 7 years usage and wouldn't turn on anymore. A local scamming plumber literally quoted me £300 including VAT or £250 cash to avoid HMRC for this job which is literally more than a plumbers day's wages minus the part. Seriously! I bought a £40 Gappo shower bar from Amazon (better quality than the old one it seems) and replaced it in 10-15 minutes. Didn't really need the cloth to be honest. Just careful spinning with the spanner was all it took but doing it bit by bit is good advice for sure. Thanks. Tip: After switching off the mains water just let both the cold AND hot water taps nearest to the shower run till they are dry before unscrewing the old bar.

Was putting this off for ages and ages. But watching this video to finally fixed it ..thanks

Excellent tutorial thank you. Clear and no waffle....all tutorials should be this good.

How good was that! A dead easy to follow video, no B/S just clearly explained. Well done fella I've just subscribed 👍

Brilliant Video! I watched a few others which were either vague, too short or too long-winded.
Very well explained and easy for novices to understand, giving us the confidence to have a go!
Nice One & Thanks.

Nice no nonsense video,well filmed and easy explanation. Thankyou for uploading.👍

Thanks for this Pouse. I've recently installed a Triton Dene Cool Touch mixer, (it has been around for a few years), and the flow control is on the right and the temperature on the left. This is the first bar mixer valve I've had and I would have thought the controls would be standardized, especially from the same manufacturer.
Thanks again, Kieron.

I'm just about to do mine and thought I best check to make sure there's nothing tricky about it - nice clear video mate, tidy!

Thanks Pouse. Just followed all your instructions and have a newly fitted shower valve.

Just followed this and fitted my new shower with ease. Thank you!

Just the video I was looking for... was going to pay a handyman to do this but I think I cam do this myself now, cheers!

Excellent.
I wish all instructional videos were as clear as yours. 👍👍

Brilliant - thanks for posting. Very well explained, no fuss, gimmicks etc just how to do it. Perfect - subbed for more!

Thank you very much, you explain very clearly, and emphasize the most important aspects. Very useful video!

Brilliant this has given me the confidence to replace my shower bar myself. I think our thermostat has broken somehow because I can feel the temperature of the hot side gets hot inside the unit but then the cold tap turns but doesn’t adjust anything and the water exiting the shower head is just lukewarm or cold. So replacement it is. Thanks for posting such clear instructions 👍😎

Mate, this is brilliant. Thank you for taking the time to make it.

Brilliant video well explained save me getting a plumber....

This looks easy enough. I’m gonna try doing it myself. The hot tap has become loose so I’ve take off the sleeve to see the thread inside has worn out and just been using pliers to turn it on and off. It’s been doing that for a year and now really won’t bite anymore. Thank you so
Much , you just helped a single mamma in the U.K. ❤. Bless your skills.
Can you please do video how to screw things like solar lights on to outdoor concrete wall please. How to know what kind of drill bit goes into the mortar . Thank you ❤. And how to hang heavy mirrors please too on plaster board, if you have any project like that coming up.

Excellent video well explained clearly for novices like me . Thanks and I’ve subbed.

On my current mixer the thermostat is on left not right so I’m wondering if I buy a new one and fit it will be still ok? You say the thermostat has to always be on the right side where cold water is… not on mine, weird, does it matter?

OMG I did it!! So thank you. Seriously. Women can do this too..... :)

Good shout on measuring between the centres first. Have a like ;)

Thanks - just saved me £120

Great video, really clear and informative. Thank you!

Amazing video! One of the best instructional videos out there

Thank you for this video, you've really given me the confidence to take on this task myself 😄

You have explained this very well
Thank you

Great video, very straightforward. I have put a new shower bar on, everything is fine no leaking but there is a whining sound on the right side if the bar, only does this when yhe temperature is medium or below if you turn it up to make yhe water hot then the noise disappears. Any suggestions. TIA

Cheers mate!! Saved me a fair few quid by doing this myself.

Super video mate.. I found this video very helpful. I found a tiny leak at 10:35; I believe its coming from between the bar valve mounting kit and the cover. Can I just use the PTFE tape here? If yes can I just tape it round about 8 times as in your other video?

Just what I needed to see. Thanks.

Big help! Great video. Off to change mine now. Thank you

Thank you for this great video. I'm about to take my mixer off as I have a dripping shower and it is driving me crazy. Do you have any tips on what I should be looking for???

This is brilliant cheers dude !

Really impressed with this tutorial, I'm going to change ours this afternoon 👍👍

Very good instructional video

Hi mate. Very good channel. You explain very good. Thanks and i would be happy for more videos.

Love your videos, you are a total legend 🙂

Pouse - Great video - really informative - really enjoyed it.

You absolute star. Saved me £60

Brilliant! Quick question….if my shower bar has a slight leak from the cold side nut….what might be causing that? Thank you!

Thank you just changed my shower using your video 👍

Great tip place a cloth over the nuts 👌

Really helpful but my worry is the hot water side on the left of mine controls the temp and the cold on the right is the flow.

Are all showers of this type of mounting now. I have old "victorian" mixer and needs replacing.. Original plumber made a booboo and has hot on right, not left. I guess its worth replacing adding the base mounting and switch hot and cold around.

great video, even in 2025! :) thank you

The inlet pipes are too short for bracket and olive to fit over. Is it possible to extend plastic piping coming out of wall or use smaller bracket to avoid having to pull up tiles

Brilliant video! Is there any extra step that needs to be taken to cut off water if you have an unvented megaflo hot water cylinder? Dont want to get burned!

Excellent video mate. Very clear instructions. Can I ask what is the difference between a thermostatic bar and manual shower faucet

My shower is running cold when it should run hot. But when the cold hand basin cold tap is turned on the shower water runs hot !. It was working fine before, any ideas. Good video.

What solution would you recommend if there is water leaking from the cover i.e. behind the bar?

Good video thanks straight and to the point

Very informative, thanks very much.

good and simple instructions , thank you.

If you shut off the water supply and remove the shower bar will the grundfos pump come on automatically. Does it have to be isolated as well.

The best explanation video ever. 👍👍

great tutorial! no messing

TA TAR...love it keep up the good work!

This is epic defo worth a go. Would this work with other types of mixer valves( other than bar) provided its 150mm between hot and cold water pipes? Thank you.

well explained sir , very usefull video. god bless you,

How do you manage to turn the cold water off? Is it usually a stopcock under the kitchen sink?

Thanks great video. When I try and disconnect the nut which attaches to the fixing kit pipe (7:15) the fixing kit pipe is turning with the nut. Very narrow space between the nut and the chrome plate round the fixing pipe so can't get a spanner in to hold against it. Any idea how I can free the nut from the fixing pipe? Job come to a halt at the moment. :-(

After removing the bar then refitting will new compression olives be required as they would have already been compressed?

great video again buy a pint when you in my part of wales

You did not explain if the actual mixer valve on the right can be changed by pricing off the control dial..or are these bar mixers one unit...? and you can't just replace the mixer valve?

I just successfully did this! Thank you.

Great vid thanks. I have a Mira 415, I think, external bar with a mixer knob in the middle. It is fed from a combi boiler. If I want to replace it (min 20 yrs old!), can I replace with any 150mm mixer, central knob, or with the knobs on the end? Don't even know if there is any difference! Also, is it just a case of turning the stopcock off to stop all water? Thanks a million!!!!

My valve is leaking from the cold side end of the valve, is it better to replace it with a new valve?

When shutting off the mains supply with a combi, do I need to drain the hot water or just run the cold tap until its dry and then remove the old shower bar?

Just bought same Triton shower but only plastic seals in the box. Do I use these instead of the felt/rubber types you used? Great video thank you.

Hi, great video. I feel confident to tackle this myself after watching this. As my old unit is unbranded, it’s virtually impossible to locate thermo cartridge as I think it’s gone in my current shower. I’m guessing it’s just as cheap and easy to replace the whole shower right? Also, if I replace with something branded, will all bar valves be compatible with the existing wall fixing kit as my wall fixing is in really good condition as only installed 18 months ago. Thanks again!

Brilliant mate!! Thank you for taking the time to do this, helped me loads!!

Excellent video. I want to instali a new Mira mixer shower but my hot and cold water pipes are outside of the wall but all of these new showers are designed for pipes retracted into the wall and covered by the tiles. Is there a way that I can install one of these type showers and attach to my external pipes? Are all the fittings on the hot and cold water threds on the mixer bar of a universal size? Thank you in advance.

IF I STOP THE MAIN WATER STOPCOCK WOULD I HAVE TO SWITCH OFF MY BOILER?

Great video, very helpful.

Is the distance between the hot and cold pipes always the same regardless of the make of the shower bar? Thanks

Hi, I’d like to change the bar valve wall mounting kit. The old one was glued to the wall. As the tiles are to hard to drill threw.
Which is the best water proof sealer to stick the new wall mounting plate to the tile. Thanks.
Also please can you post a link to a video on how to replace a wall mounting kit. Thanks for doing this video

What's the best way to access the pipes behind? I think I have a leak in the pipe buried in the wall.

☺ Brilliant video ! See from your more recent videos that you are still out there 😁 Please can you tell me the felt washer size for the cold inlet ?

Thanks, a really helpful tutorial , very clear , even for a duffer like me . Job done :)

The hot water comes from combi boiler, will turning Cold supply off also turn supply from combi boiler off, thanks.

Are the wall mounted kits universal between different manufacturers?

Great video. Got a drip from the shower head, would a replacement bar or atleast replacement of all the washers do the trick?

Brilliant mate thanks very helpful and well explained 😊

Hi Pouse, I need to replace my bar valve. I have seen some versions where the temperature control is on the left and the on/off control on the right. So these would not work for the typical installation? My current valve has the on/off left and temperature on the right, just as you described. Presumably I must get the same arrangement?

I have water coming through from where the shower hose attaches to the bar. This is when the shower is on or off so i have had to turn water supply off completely. Any ideas what could be the problem? Thanks

Perfect tutorial, thanks

Hi buddy could you give me some guidance or point me in the right direction i have a shower similar to this now when having it turned to full heat it doesnt get very hot i have tuck side off and adjusted it to max still the same but i have noticed to get the shower to go nice and hot if i simutaniously run the cold tap in bath the showers goes nice and hot then any ideas

all looks so simple, but my new shower would not screw on up to the circle things on the tiles, what am I doing wrong ?

For a gravity fed system do I just have to isolate main stopcock under kitchen sink and run water till nothing there? Just asking as no gate on pipe coming out top of vented cylinder. Cheers

My supply is hot left and cold right - but my controls are temp control left and flow control right, I assume that’s just a design thing? All the potential replacements I’m looking at are the opposite though - it’s definitely not upside down either 🤔

Are all these thermo bars the same temp wise? Just had a new one fitted and it doesn't get hot enuff for me. I was thinking if they get hotter the more u spend then it might be worth me buying a different one.
