Let‘s Find the Perfect Shower Control Heights for You

Installing shower controls at the right height is crucial for comfort and accessibility. With all the different shower components out there, it can get confusing! As your home improvement expert, I‘ve put together this comprehensive guide to walk you through the standard heights for shower handles, showerheads, and more.

I‘ll provide plenty of tips, statistics, and code references to help you make the best choices when outfitting your dream shower.

The Magic Number for Shower Valves

The most important shower control height is the shower valve/handle. This should be:

• 42 to 48 inches above the floor
• Measured to the center of the valve

This range makes the shower valve accessible for users of different heights.

According to a study by Michigan Medicine, the average man is 69 inches (5 feet 9 inches) tall, while the average woman is 63.5 inches (5 feet 3.5 inches) tall. With the valve at 42-48 inches, most adults should be able to comfortably reach it.

For reference, ADA accessible showers require handles to be no higher than 48 inches maximum. This ensures accessibility for wheelchair users and those with disabilities.

Easy Location for Shower Valves

When planning your shower, make sure to:

• Locate the valve/handle on the side wall out of the shower spray.
• Position it far enough from the shower head – minimum 6 inches – so you can adjust temperature easily.
• Consider other fittings like grab bars, shelves, soap holders etc when picking the location.

You‘ll want a nice open space around the valve for easy access.

Dialing in the Right Temperature

The shower temperature controls should be a little higher than the main valve/handles:

• 48 to 54 inches from the floor
• This makes them easy to reach but keeps them out of the main spray zone

Again, you‘ll want to position the temperature controls off to the side of any shower heads or body sprays.

Having the temperature control 3-6 inches above the main valve allows you to adjust both comfortably. The ADA maximum height for temperature controls is also 48 inches.

Let‘s Talk Shower Head Height

Finding the right shower head height is an art – too high and washing your hair is a nuisance, too low and you‘ll be hunched over!

The standard height for shower heads is:

• 65 to 72 inches from the floor
• Measured to the shower head outlet/spray nozzle

But you‘ll want to fine tune this based on the ceiling height:

• With a lower 8 ft ceiling, stay around 65-68 inches
• For higher 9 ft+ ceilings, consider 70-72 inch shower heads
• Really tall people may want to go even a bit higher if possible

What Does the Code Say?

For ADA accessible bathrooms, the maximum shower head height is 48 inches above the floor. This makes it usable from a seated position.

The American Society of Mechanical Engineers in Standard ASME A112.18.1/CSA B125.1 indicates the maximum shower head height should be 80 inches to prevent the need for a stepladder!

Mixing Valve Regulations

Proper water temperature regulation is crucial for safe showering. That‘s why the International Plumbing Code (IPC) mandates:

• A thermostatic or pressure balancing mixing valve on all showers
• Installed at the standard shower valve height
• Mixing hot and cold supply to 120°F max

This prevents dangerous temperature fluctuations that could lead to scalding.

How Do Mixing Valves Work?

Mixing valves blend hot and cold water flows to deliver a consistent, tempered output temperature to the shower head. This keeps you safe if the cold or hot water supply changes pressure.

Make sure your plumber properly installs and adjusts the mixing valve during shower installation.

Electric Shower Installation Tips

More homeowners are opting for convenient electric showers powered by an electrical heating element. But these require proper installation by a certified electrician.

In the UK, all electric shower installs must comply with:

• Part P Building Regulations for electrical safety
• IET Wiring Regulations (BS 7671)
• Water Supply (Water Fittings) Regulations 1999

The electrician must provide an Electrical Installation Condition Report before and after installing your electric shower.

Key Electric Shower Requirements

• Isolation switch no more than 2 meters away from shower
• Switch must fully disconnect power when off
• 3+ meters distance from any source of hot water
• Follow all manufacturer instructions

This ensures your new electric shower is safe and compliant.

Flexible Shower Control Placement

While the standard position is on the side wall, it is possible to install shower controls on the opposite wall from the shower head:

• Use a diverter valve system with offset inlet and outlet ports
• Divert the controls using long tubing if needed
• May require relocating supply lines and electrical

The difficulty depends on the wall type:

• Easier for standard drywall or tile walls
• Harder if crossing an insulated or stud wall

Off-wall control placement offers more flexibility in designing your dream shower!

How Far Back for the Valve?

Wondering how far from the wall surface to place the shower valve during rough-in? The standard is:

• 12 to 16 inches from finished wall surface
• To the valve‘s center point

This allows enough space for the valve body and provides ample room for trims, handles, and the finished wall surface.

Of course, the position may vary based on the wall stud depth and type of valve:

• Adjust for studs thicker than 14-16 inches
• Space multiple valves appropriately (e.g. 3-valve showers)

Shower Valve Installation Tips

• Make sure valve will fit with your choose trim kit before installing
• Use careful measurements during rough-in to get placement right
• Seal the wall penetration to prevent moisture damage

Getting the valve in the proper place takes planning but prevents issues down the road.

Curbless Showers: A Tricky Proposition

Curbless or curbless showers with zero entry and no raised threshold are popular for a sleek, open look that flows into the rest of the bathroom.

But these take special expertise to install correctly:

• The shower floor must slope just enough to drain without going overboard
• Usually requires a linear drain along the entire side or back wall
• Needs waterproofing for the open sides
• Not permitted in some areas without a curb

Consider working with a professional if you want the curbless look. Improper installation can lead to leaks and water damage.

If designed well, curbless showers provide an accessible, modern style. But traditional showers are often easier to install.

Ceiling Mounts: An Effective Height Booster

Installing your shower head on the ceiling is a great option if you need more height:

• Can position the head up to 8-9 feet above the floor
• Allows for comfortable usage even for very tall users
• Make sure it‘s directed straight down or angled away

The downside is that ceiling mounts often require you to permanently fix the shower head height. Handheld mounts allow more flexibility.

Watch Your Head! Issues with Shower Heads Too High

While a high shower head may work for very tall users, too high can be uncomfortable:

• Having to tiptoe or crouch to wash your hair is no fun!
• Maximum height is roughly 6 inches below ceiling level
• Can make it hard for kids or shorter adults to use

If multiple people will use the shower, keep the height reasonable for the shortest person. Or consider an adjustable slide-bar setup.

Mixer Bar Placement – What‘s Best?

Many modern showers include a full-length mixer bar with multiple outlets rather than a single shower head.

For mixer bars, aim to position them with the water outlets at:

• Shoulder level – This makes adjusting settings and using the attachments comfortable
• At a height reachable by all users
• Taking into account the shower layout (corner, neo-angle etc)

The bar should be high enough to allow standing upright but not so high you have to reach up or hunch over.

How Much Slope? Getting Drainage Right

Effective drainage prevents pooling water in your shower. But too much slope can feel uneven underfoot.

General guidelines:

• Tile showers: 3-4mm of vertical drop per meter
• Standard tubs/showers: 2-3mm per meter

More slope helps if going curbless, using linear drains, or installing in a wet room. Insufficient slope impedes drainage.

Consult plumbers or look up codes for exact standards. Some key factors:

• More slope needed for larger showers
• Should be consistent slope toward drain point(s)
• Cut a slope into the subfloor when installing

Getting the shower pan slope right takes careful planning but prevents headaches later.

Why Walk-In Showers Need A Curb

Unlike curbless showers, traditional walk-in showers require a raised curb around the perimeter.

Good reasons to include a curb:

• Contains water in the shower pan and prevents splashing out
• Provides support for shower walls and reinforcement for the pan
• Required by code for adequate waterproofing in many areas
• Gives a finished edge to the shower entryway

Standard curb height is 2-3 inches for showers, higher for larger enclosures. Curbs often have openings to allow wheelchair entry while still retaining water.

Mixing Valves: Mandated by Code

Earlier I mentioned mixing valves. Most plumbing codes actually require them, for good reason.

For example, the International Plumbing Code (IPC) states:

"Hot water shall be delivered to bathtubs and whirlpool bathtub appliances at a temperature not exceeding 120°F (49°C)."

And that:

"A thermostatic mixing valve conforming to ASSE 1070 shall be installed at the hot water source…"

This prevents scalding accidents. Don‘t skip this crucial safety device!

Centering the Valve with the Drain

One last tip – when roughing in the shower, make sure to:

• Center the shower valve with the drain location
• Allows water to flow evenly to the drain
• Prevents leaking, flooding, and mold growth

Having them aligned also makes finishing the walls and plumbing much simpler.
