Shower valve

[Sumboodie]

2 valve cheap setup that scalds if something uses water.

To convert to a lever style with 2nd lever for temp, what do I buy?

Like Delta 17 series.

Buy the handle, plus valve, plus cartridge? And 2 to 1 handle trim plate?

I "just" by moen. Someone will be along with other answers.
Moen has self-regulating temp valves (posi-temp).

But what handle goes with what?

Why isn't it all together like a kitchen spigot?

But what handle goes with what?

Various handle styles and colors. You match have to match the handle type to the valve type:

Single Handle Shower: PosiTemp Valve

A Single Handle Shower: PosiTemp Valve will have a lever handle or knob. The lever handle will rotate for hot and cold water. The escutcheon screws (back plate behind the handle) will be located at …

solutions.moen.com

(I didn't verify all these fit the valve I mentioned, but you get the idea)

Moen offers dual controls if that's your preference too. But the selections of handle type are more limited.

 

[Sumboodie]

Looking for the setup that hot/cold is on a control and water flow on another.

That's what my old place had. I rarely had to fiddle with the temp setting, just reach in, kick it on wide open and wash.

If the current valves function and the trims are OK, you can just install a thermostatic mixing valve on tbe hot side. I did this in the kids bathroom at my last house that had a 2 handle setup. Max temp of 105 made it zero risk of scalding

Current setup is this...

Looks like this is how Moen handles it too, two separate valves. The dual-valve assemblies mostly appear to be diverter on the secondary.

Really, too many options here!

Delta setups require valve body purchase and corresponding trim purchase. Trims come with cartridge.

Example, this uses a R10000 valve body:

Familiar geometries and subtle curves in the Tetra™ Bath Collection combine to bring a sleek, architectural look and feel to the bath. Lumicoat™ Finishes...

But as others have said, you only really probably need a thermostatic mixing valve to accomplish what you want. But either method requires a full swap of the in-wall components with your current set-up, so each requires approx. the same effort.

Edit to add that you should really select your trim first, then pick the corresponding valve body.

This is the style I used, installed it in the basement.

See the item I linked. Didn't have to touch any of the in wall components. Just intercepted the hot feed

Needs to have the pressure/temp compensation setup that most valves have.
It also goes ice cold, it's not just a heat issue. Water heater is at 120* already.

Temp changes with water usage and pressure.

The current setup *****. Constantly fiddling with the knobs to keep the temp decent.

I didn't have lots of pressure fluctuations, but I did find that with this and a freshstem/valve, it was quite stable and eliminated the sudden hits of hot water that I was having. We'd turn the shower on full hot and not mess with it. Maybe it's not the right solution for you though.

Map out your hot water system. I think you have a poorly designed/installed piping system. You do have to have temp and pressure balance equipment but when the flow slows down the equipment is surging or slugging you with H/C water. is the cold supply to the building close to the shower and the water heater on the other side of the house? I’ve seen this quite frequently when the pressure drop in the hot piping vs the low drop in Cold gives the result you are living with.

Nope. Well feed and water heater are next to.each other.

 

[Jackfre]

Glad we got that straightened out

 

[evildky]

I have a delta single handle. it's got a valve that keep the balance even if someone flushes a toilet or runs whatever. Delta and moen cartridges are interchangeable, the moens are a bit cheaper, the dress up parts for delta seem a bit nicer, the body and valves are identical.

 

[Kpaige]

Remember with a lot of these new valves they not only control temp but conserve water. Sounds great till your shower only outputs half pressure!

 

[housewolf]

All I can say is good luck with it. I’ve been doing this for my whole career and it took me a week (no kidding) to select and order the pieces I needed to do my shower. They may still sell them but moen, Kohler, Delta, etc… used to sell a “tract pack” that came complete but I don’t think you’ll find that if you’re going with separate temp valve & volume control valve(s). You may find pre assembled “kits” on build.com. This is what I ended up with, each piece sold separately. Each volume control valve serves a separate device(s). One for body sprays, one for the handheld, and one for the overhead. Can use all or one/two at a time and adjust volume of each separately. The 3/4” temp control valve (left) adjust temp only and is usually not adjusted.

Volume control at the valve? I've only seen it at the head

On its way. Was about $160 all said and done.

My shower valve of choice is the Moen PosAtrmp.
Other companies make good stuff too, but Moen is my Go To for faucets and shower valves. Mrs Nadogail chose a Delta for our master bath and it has been working fine.

 

[ycgoat]

If you have scalding water you may consider turning the hot water heater temp down

 

[FredWanaker]

probably already said but later Delta etc have different cartridges that go in the valve depending on what one wants it to do. They have pressure regulated inserts and pressure/temperature regulated inserts. Part of my guess is that you don't have a functioning pressure regulator on the house. I know that when I added a house PRV most of that wild temperature swing problem went away. When the new pressure regulated valve bodies were installed a couple years ago on a remodel, the temperature swing issue completely went away.

Buy a name brand shower valve of your choice,

Might want to look at Moen and Delta cartridges again, not interchangeable, totally different body designs.

The best setup is what I installed in my travel trailer and boat: a Grohe thermostatically controlled valve. One handle controls temperature (you cannot get scalded) and the other handle controls on-off-flow. I made the polished stainless wall-mount.

It's at around 120*

How's it flow to the shower head? Seems like it's missing that part?

This seems to be mitigated by a number of things. All of our Moen fixtures had water flow limiters on them (I assume this is some federal or CA thing). Easy to remove, but we kept them as our water is limited.

UPONOR pex fittings have better interior flow diameter than others, but showers should flow just fine if the plumbing was done right.

I would guess a hose out the bottom to a hand held shower. Not my cup of tea, but typical in RV's.

This. Not installed when the photo was taken. Very handy for both showering as well as cleaning the shower and toilet.

I have a hand shower, but it's fed off the normal overhead wall pipe.

Maybe that unit will work. Was $50 online.

My mistake, Peerless. I always buys the Delta parts but my plumber buys the peerless body and valve, then the Delta trim kit.
