1. Delta Faucet R10000-UNBX Multi-Choice Tub and Shower Valve

Delta R10000-UNBX is a respected, well-known brand. It has good quality merchandise in a huge variety of looks and styles. Among them are tub and shower valves.

Well, the R10000 series is pretty much the gold-standard of Delta shower valves. And one model that stands out is the UNBX.

Okay, this is valve body only. Hence, you can pair it with your favorite Delta shower trim and cartridge. But how compatible it?

I must say, this shower valve body offers wide-range compatibility. It fits multiple shower styles and trims options. For instance, it fits most Delta dual-function, single-function, and dual-function thermostatic trim kits.

Still, it is compatible with the different connection types. It accepts IPS, Universal, and PEX connections.

Indeed, Delta R10000-UNBX is one rough-in with unlimited possibilities. Such flexibility makes it easy to upgrade the style and functionality of your steam shower.

The heat-resistant pressure test cap is another stand-out feature. It allows you to install and pressure test without the need for a cartridge or finished handle.

Installation is a breeze, thanks to the square-shaped plaster guard and flexible bracket. The plaster guard is pretty much a plastic frame that allows for simple 90 degrees cuts. Thus, with a few tweaks, it sits flush with the face of the tile.

The brackets are flexible enough to fit on surfaces that are not perfectly flat or square. Still, it is strong enough to provide a sturdier anchorage that does not rock.

For your attention, R10000-UNBX accepts ½-inch universal inlets. It works with copper and iron pipes with PEX or CPVC adapters.


The versatility you get in this shower valve is pretty impressive, especially how it accepts single, dual, and dual-thermostatic cartridges. Indeed, it is the best budget shower valve for your soaking tub.

2. Kohler K-GP77759 Mixer Pressure Balance Shower Valve

As far as originality goes, few brands can match Kohler. It is for this reason that Kohler products offer peak performance and longevity.

Well, this shower valve mixer cap is no exception. It promises years of leak-free performance as well as addresses water temperature issues.

The safety stop provides temperature control to prevent scalding. Moreover, it is easy to adjust using an Allen wrench.

Now, this mixer cap is for ½-inch pressure balance valves, specifically Rite-Temp shower valves. It works great, no doubt. However, I recommend using it alongside the GP500520 insert for the best performance. It will save you the frustration of taking it apart twice.

Other than that, this mixer cap comes with everything, including O-rings for a complete swap-out. It is easy to install, and pretty much any DIYer can do it.

Well, there are only two top mounting ears. It is quite unlike the R10000-UNBX, which has top and bottom mounts for proper attachment. Still, it hooks up easily, and the spacing is great.


I think the Delta R11000 shower valve provides the easiest plumbing ever. It is super-adaptive, accommodating all types of plumbing methods. It is easily the best shower diverter valve on the list.

Though it requires a valve trim, this pressure-balance valve comes with everything, including the mixer cap. So, you do not need to buy lots of extras.

I like how it cycles between hot and cold modes, always keeping the temperature below 120 degrees. It not only provides temperature regulation but also scald protection.

Noteworthy, it maintains the water temperature within +/-3 degrees Fahrenheit. It is such precision that makes it one of the best pressure-balance valves on the market.

The diaphragm design is quite a handy feature. It virtually eliminates freeze-ups, whether from water debris or contamination. Hence, smooth operation is guaranteed.

Perhaps the first thing that gets your attention is the rugged durability of this pressure-balance valve. It has a seemingly beefier brass construction built to last a lifetime.

This valve has a handle that cycles between hot and cold. Moreover, I like the accuracy of the safety stop and how it keeps the temperature constant. The valve guarantees that the temperature stays steady within 3 degrees all the time.

6. Delta Faucet RP1991 Shower Cartridge Repair Kit

Delta RP1991 is a generic product. That pretty much explains the ridiculously low price. After all, similar OEM products cost more than double.

But while a lot easier on your pocket, the performance and quality are worth more. It is pretty much a steal and possibly the best budget shower cartridge out there.

Unlike the original RP1991cartridge, it tends to use a bit more plastic, making it lighter. It, however, works perfectly, providing excellent scald protection. Also, it shuts the water completely in the off position. This shower cartridge is super easy to install. Indeed, you will have a working shower in minutes.

Well, this repair kit is for those with Delta 1600 Series single-handle tub and shower valve. The package includes the scald-guard cartridge and a pair of cartridge seats and springs.

Pfister is among the most trusted names in the plumbing industry. And for a pioneer of the flow-Matic valve, this is one brand that certainly stands out.

This 3-handle rough-in valve is among its best inventions. Unlike the single-handle design, it allows you to adjust hot and cold water individually.

It does have plastic parts. However, the heavy-duty brass casting pretty much overshadows it. Indeed, the quality is outstanding and designed to last a lifetime. Moreover, it provides an ultra-seal fit.

8. Kohler K-304-KS-NA Rite-Temp Pressure-Balancing Valve

It is easy to mistake this pressure-balance valve for the Kohler K-304-K-NA. Still, there is one difference that sets them apart.

The K-304-KS-NA, unlike the K-304-K-NA, has a screwdriver stop. So, should you need to do maintenance, you do not have to turn off the main water line. Instead, the screwdriver stop allows you to cut off the flow right at the valve itself.

Hence, between the two, the K-304-KS-NA pressure-balance valve gives an easy time during maintenance. Other features, however, remain constant between the two models.

Like the K-304-S-NA, this pressure-balance valve has temperature adjustment for scald protection. Of course, it comes pre-set. Still, you can raise the temperature a bit to get the water slightly hotter.

I like how the valve keeps the water temperature steady at different pressure. It maintains the temperature to within 3 degrees, keeping it below 120 degrees at all times.

Large internal ports make this a high-flow pressure-balance valve. It dramatically cuts the time you need to fill your tub. Also, you can do a back-to-back installation for even higher-volume jobs.

The diaphragm design is another outstanding feature. It eliminates freeze-ups, either from water debris or contamination.

The valve comes complete with mounting tabs, hence making installation a breeze. But like the K-304-K-NA, you need to purchase the trim separately to complete the unit.

As for connection types, this pressure-balance valve accepts Universal NPT and direct sweat connections.

Danze is a global leader in product design. Aside from the striking designs, this is a brand that guarantees value, performance, and uncompromising quality. Such are the specs you get in this pressure-balance valve.

It is a single-control mixer valve, complete with a diverter and stops. The screwdriver stop, in particular, eliminates the hassle during maintenance by shutting off the water directly at the valve.

I like the temperature limit adjustment. It keeps the water temperature steady and at a safe level to prevent scalding.

Like Kohler valves, the Danze pressure-balance valve supports the back-to-back installation. As such, it is suitable for unique and high-volume jobs.

The valve comes standard with a plaster-guard and mounting brackets. As such, it is quick and easy to install.

Danze D113000BT supports sweat ½-inch inlet and outlet connections, and IPS 4-port hook up.

I like the heavy-duty built of this pressure-balancing valve. Performance-wise, I consider it one of the best pressure tank regulations and silencing loud showers. If you are looking for the best shower diverter, Grohe 35015000 is among the models I recommend.

Best Shower Valve: Complete Guide

Construction Material

Ensure you choose a shower valve that comes in leak-proof, rust-resistant materials. Also, it should be corrosion-resistant, should you want the best shower valve for hard water.

Brass is a solid bet for shower valves as it is unlikely to leak or corrode. Also, it lasts pretty much a lifetime, making it worth the extra cost.

Stainless steel is another excellent choice. However, ensure you go for high-grade stainless steel. Though a little pricier, the cost is worthwhile.

Type of System

There are three types of shower valves: thermostatic, pressure-balance valves, and diverter valves.

A manual or pressure-balancing valve is the most common type. It is typically for balancing pressure, though it may also vary the water temperature.

Thermostatic valves, though slightly more expensive, control both the water temperature and pressure. Unlike pressure-balancing valves, it allows you to control the temperature accordingly to prevent uneven fluctuations. Also, it has a volume control to adjust the flow rate.

Between the two, thermostatic shower valves provide the most comfortable. As such, it is the best option for the elderly, disabled, and kids. But should you not have the problem of fluctuating water temperature, you will do fine with a manual pressure-balancing valve.

The third option is the diverter valve. Shaped like a T, it joins different water taps and has a lever that shifts the flow from one tap to another.

Control Levels

Control levels determine how best you can set the water temperature and pressure. As far as control levels go, there are three types of shower valves: single-control, double-control, and triple-control shower valves.

A single-control valve only gives you the option to adjust the water temperature. Once it achieves the desired temperature, it maintains that level until you turn it off.

A double-control valve works more like a single-control valve. It does, however, give the option of adjusting both the water temperature and pressure.

A triple-control valve is the most versatile. It has three controls for water pressure, water temperature, and outlet selection. It, however, tends to work best with fancy trim kits comprising multiple outlets.

Installation Type

We have two shower valves based on the installation type: exposed and concealed shower valves.

Concealed shower valves sit in a recess behind the wall. It provides flexible placement of valves and outlets. Also, the invisible working parts make it a stylish choice for modern bathrooms. However, it is pricier and expensive to install.

Exposed shower valves have visible working parts. They are budget-friendly and easy to install. However, the design options are limited.
