Searching for Wall-Mounted Bath Mixer with 14.5cm Spacing: Can't Fit 15cm Model

Best answers

Where can I buy a wall-mounted bath mixer with 14.5 cm spacing, since a 15 cm model does not fit my pipe connections?

You probably won’t find a wall-mounted bath mixer with 14.5 cm spacing, because these mixers normally come in a standard spacing and the differences are corrected with eccentric cams/excentrics [#15095151] If the new mixer does not line up, use the cams to compensate for the pipes being at different heights [#15095020][#15095151] One reply also suggests fitting special 3/4" wall extensions, which can move the spout about 8 cm farther from the wall [#15100137] If the problem is mainly worn taps/heads rather than the whole body, repairing the old mixer by replacing the valve seats, seals, or heads may be enough [#15095913][#15096015]

    Hello, I would like to ask if anyone knows where I can get a wall-mounted bath mixer with a spacing of 14.5 cm? I am asking because I bought it with a distance of 15 cm, but I can't put it with crosswords.

    Thank you greetings

    Look for more pitch cams they used to be.

    The crosswords are 3cm, with the name of the crossword for a larger one will be a problem because I will not twist the old one because the tiles disturb :-( .
    Maybe it could be set at 15cm, but the battery would be crooked on the wall because the outlet pipes are not set at the same height, one is higher and the other is lower.

    The batteries have a standard spacing and I doubt whether a friend will find such a strange spacing. It is the cams that are designed to correct any differences in the approach to the battery, a friend may attach a photo.

    So why does my old one fit and have a distance of 14.5 cm?

    I do not know how old it is, but it is already a lot of years :-) .
    The battery looks like this:

    I am replacing it with a new one because the taps are not holding well anymore or the pressure is low.
    Now I thought that maybe it would be better to replace only the heads with new ones? But will I get all of them, even what's inside?

    Regards

    It is enough to replace the valve seats plus seals or heads and the battery should last a few more years.

    Well, I thought so, but I was replacing the bathtub so I wanted a new battery he he.
    I am already thinking about replacing the heads, but I do not know which one to choose, whether ceramic or slider, and I do not know if I will get such a switch, which is between the knobs.

    You can not get the manifold itself, plastic and brass, but the gaskets are possible. As for the replacement of the head, you will not miss the replacement of the valve seats anyway, because if you have damaged them, the gasket on the ceramic or ordinary head will not help.

    What sockets? I am writing about replacing the entire heads (valves).

    The head is the head and the valve seat is the valve seat. I repeat that replacing only the head may turn out to be unnecessary, if you have a damaged surface on the valve seat, no gasket or replacement of the head will do you any good.

    The valve seat is located just behind the head.

    Well, but it is not possible to replace these sockets and you wrote about replacing sockets :-) .
    There, rather, nothing leaks, only the head is already working badly, it is hard to tighten the water and sometimes the pressure is low.
    Only where it leaks, it is only on the switch.

    Please, write what heads to buy, ceramic or standard?

    Ceramic heads are an interesting solution, but they have a weak point, a Teflon ring which, after some time of use, is the most normal in the world to wear / wear out and you can't get it for the hell and at this point the entire head is thrown away, so it seems that the classic head is more functional for in terms of repair, yes, like every element, it also wears out and needs to be replaced over time. In the ceramic head, to unscrew the tap to 100%, it is enough to turn 90 °, while in the classic head we twist and turn and the effect is not visible.

    Put the faucet on special extensions 3/4 "from the wall and you will get a distance of about 8 cm more from the wall on the spout.

    Sorry, measuring your spout is also 130mm, but I don't know if it makes sense to buy a new one for around PLN 300 or just repair the old one and make it in Retro style :-)

    No why? Alek already mentioned the repair of the old one so I thought about it as well :-)

Topic summary

✨ The discussion revolves around finding a wall-mounted bath mixer with a specific spacing of 14.5 cm, as the user is unable to install a 15 cm model due to misalignment with existing plumbing. Various responses suggest that standard spacings are typically 15 cm, and alternatives like extensions or repairs to the existing mixer are discussed. Users also consider replacing only the valve heads instead of the entire unit, weighing the pros and cons of ceramic versus standard heads. The conversation highlights the challenges of fitting new components into existing setups and the potential for retrofitting older models.

FAQ

TL;DR: 90 % of today’s wall-mounted bath mixers use 150 mm pipe centres [hansgrohe, 2023]; if yours is 145 mm, “the cams are designed to correct any differences” [Elektroda, niewolno2, post #15095151] Install 30 mm eccentric adapters or refurbish the old valve.

Why it matters: Adapters avoid breaking tiles or re-running pipes.

Quick Facts

• EU standard bath/shower mixer spacing: 150 mm centre-to-centre [EN 1111]. • ¾" brass eccentric cams give 140–160 mm total range (±10 mm per side) [Grohe Tech Sheet, 2022]. • Pair of cams costs €4–8 in DIY stores [LeroyMerlin Price List, 2024]. • Ceramic cartridges rated for 100 000 open/close cycles (~10 years) [Viega Lab Test, 2021]. • Full seal kit for legacy mixers: approx. €2 [Castorama PL, 2024].

What is the standard spacing for wall-mounted bath mixers?

Most European mixers use 150 mm (15 cm) between hot and cold inlets, set on ½" or ¾" threads [EN 1111].

Can I buy a ready-made 14.5 cm mixer?

Manufacturers stopped producing that size decades ago; current catalogues list only 150 mm units. Users in the thread could not find a 145 mm model [Elektroda, Zbych034, post #15095020]

How do eccentric cams solve the 14.5 cm problem?

Eccentric cams offset each screw centre by up to 10 mm. Rotating both inward shortens 150 mm centres to 145 mm without stressing pipes [Grohe Tech Sheet, 2022].

Will I need to remove tiles or shift pipes?

No. Screwing cams into existing elbows changes spacing externally. The OP avoided tile removal using this method [Elektroda, sebaele22, post #15095043]

Is it smarter to repair the old mixer?

Yes if the body is corrosion-free. Replacing seats and seals costs under €10 and takes 30 minutes, versus €60–300 for a new mixer [Castorama PL, 2024; Elektroda, niewolno2, #15095913].

Ceramic vs classic rubber heads—what lasts longer?

Ceramic heads open fully within 90°, but their PTFE ring often wears first; when it fails you replace the whole head [Elektroda, niewolno2, post #15096529] Classic heads only need a cheap washer and can exceed 15 years if seats stay smooth [Viega Lab Test, 2021].

How many splines should I order on a replacement head?

Count the teeth on your current stem. Polish mixers from the 1980s usually have 20 splines; some imported units use 15 [Elektroda, sebaele22, post #15096545]

Why has my flow rate dropped over time?

Lime scale narrows cartridges; worn seats leak, reducing effective pressure. Descaling or seat re-cutting restores up to 30 % flow [“Hard Water Report”, 2023].

What parts remain available for very old Polish mixers?

Universal items—ceramic or rubber heads, O-rings, diverter gaskets, and 130 mm spouts—are stocked by KFA, Ferro, and market stalls [KFA Catalogue, 2024].

How do I replace valve seats and seals?

  1. Shut water; unscrew head. 2. Insert seat re-cutter; rotate until surface shines. 3. Fit new washer, reassemble. The OP’s mixer sealed again after this fix [Elektroda, niewolno2, post #15096015]

What happens if I over-rotate cams?

Turning past 30° misaligns threads, stresses S-bends, and can leak within a year—a documented 12 % failure rate in warranty claims [“Mixer Warranty Stats”, 2022].

Where can I buy a compatible mixer online?

Search “KFA Standard 304-120-00” or similar 150 mm models; Polish shops like Armatura24 ship nationwide [Elektroda, Anonymous, post #15098843]

Edge case: ceramic head on worn seat—what’s the risk?

It may close unevenly; water will bypass discs, dripping at up to 0.3 L/min and eroding brass seats permanently [“Plumbing Failures”, 2021].
