Understanding Exposed Showers

This guide delves into the world of exposed shower mixers, exploring their advantages, considerations, and how they can elevate your shower experience. We’ll equip you with the knowledge to determine if these classic valves are the perfect fit for your bathroom.

Exposed shower mixers, also known as manual or external shower valves, offer a classic and straightforward approach to shower control, making and installing them a popular choice for many homeowners in London.

Here’s a complete, comprehensive guide to these mixers, helping you decide if they’re the perfect fit for your dream shower:

What is an Exposed Shower?

 

Unlike concealed showers with shower valves hidden behind the wall, exposed shower mixers showcase their functionality with the valve body and controls mounted directly onto the shower wall.

This creates a traditional and familiar aesthetic, often featuring two separate levers or knobs – one for hot water and another for cold. By adjusting these levers, you manually mix the hot and cold water to achieve your desired temperature.

How does an exposed shower mixer work?

 

It offers a straightforward and easy-to-understand approach to controlling your shower temperature.

They operate water pressure and temperature separately, allowing users to adjust their preferred shower heat and pressure. The thermostatic control installed ensures a consistent and safe showering experience. They deliver a precise temperature every time, using bi-metallic thermostatic technology. Here’s how it works in detail:

Internal Mechanism:

  • The exposed shower mixer houses two internal cartridges, one for hot water and one for cold water.
  • These cartridges are connected to separate inlets for your hot and cold water supply lines. ( concealed counterparts)

External Controls:

  • On the polished chrome exposed part of the valve, you’ll typically find two separate levers or knobs – one for hot water and another for cold water.
  • These levers or knobs are connected to spindles that control hot and cold water from their respective cartridges.

Mixing the Magic:

  • By turning the hot water lever, you increase the flow of hot water entering the mixing chamber within the valve.
  • Conversely, turning the cold water lever increases the flow of cold water into the mixing chamber.
  • There’s no single “mixing lever” here. You control the temperature by adjusting the balance between hot and cold water flow through these individual levers.

Safety Features of Exposed Shower Valves

Most exposed valves are thermostatically controlled to prevent sudden changes in temperature. Thermostatic control ensures a consistent and safe showering experience. Exposed shower valves with thermostatic control are a safer option for showering. They provide a precise temperature every time, using bi-metallic thermostatic technology.

 

Delivering the Perfect Temperature:

  • The mixed water from the chamber then flows out to your showerhead or other outlets.
  • By adjusting the hot and cold levers simultaneously, you can achieve the desired water temperature for your shower.

Thermostatic vs. Manual:

  • Most exposed shower mixers are manual, meaning you control the temperature by adjusting the levers yourself.
  • However, some models may offer a thermostatic option. These feature a thermostatic cartridge within the valve that automatically mixes hot and cold water to maintain a pre-set temperature, offering more precise control.

Benefits of Exposed Shower Mixers:

  1. Simple and Affordable: Exposed shower mixers are generally easier and less expensive to install compared to concealed valves. Their straightforward design requires less labour and eliminates the need for complex in-wall plumbing modifications.
  2. Easy Maintenance and Repairs: Since the valve body is readily accessible on the wall, repairs or replacements become a breeze. This can save you time and money in the long run compared to concealed valves, which might require opening up the wall for access.
  3. Traditional Elegance: Exposed shower mixers offer a timeless aesthetic that complements various bathroom styles with an extensive range. Their classic design adds a touch of charm and functionality, particularly in traditional or vintage-inspired bathrooms.
  4. Wide Variety of Styles: Exposed shower mixers come in a wide range of finishes and designs, allowing you to find the perfect match for your bathroom décor. From chrome and nickel to brushed brass and matte black, you can personalize your shower with the ideal aesthetic touch.

Things to Consider with Exposed Shower Mixers:

  • Space Usage: Exposed shower mixers take up wall space and might feel visually intrusive in very small bathrooms. Consider the available space in your shower area before making your decision.
  • Temperature Control: While some exposed shower mixers offer thermostatic options for precise temperature control, some may be simpler models with manual mixing. If consistent temperature is a priority, ensure you choose a thermostatic exposed mixer.
  • Durability: Opt for high-quality and well-established brands like Bristan, Aqualisa, Triton, or Mira to ensure durability and reliable performance over time.

Time for a Change? Signs Your Shower Mixer Needs Replacing

Is your once-reliable shower mixer causing frustration? Here are some telltale signs it might be time for a replacement:

  • Temperature Fluctuations: Inconsistent or uncontrollable water temperature is a major red flag. A faulty exposed shower valve might struggle to maintain the desired temperature.
  • Dripping or Leaking: Persistent drips or leaks around the mixer valve indicate worn-out parts or damaged seals. Ignoring leaks can lead to water damage and higher water bills.
  • Stiff or Loose Levers: Difficulty adjusting the water temperature due to stiff or loose levers can be a sign of internal wear and tear in the mixer valve.
  • Reduced Water Pressure: A noticeable drop in water pressure could be caused by a faulty mixer valve restricting water flow.
  • Visible Damage: Cracks, corrosion, or visible damage on the mixer valve itself are strong indicators that it needs to be replaced for both functionality and aesthetics.

Exposed Shower Valve Installation

Complete bathroom installation with modern fittings

Exposed shower valves are easy to install, making them a great choice for any bathroom. The process is straightforward for a professional. Exposed shower valves are designed to last, making them the ideal choice for family bathrooms.

While the inner workings of an exposed front shower mixer valve are relatively simple, installation requires a qualified plumber for several reasons:

Plumbing Expertise: Connecting or replacing the exposed shower mixer to your existing hot and cold water supply lines requires expertise in working with different connection types like compression, BSP (British Standard Pipe), or PEX. A plumber will ensure a secure and leak-free pipework connection.

Regulation Compliance: Building regulations in the UK ensure safe and efficient plumbing systems. A qualified plumber will guarantee your exposed shower mixer installs adhere to all relevant regulations for peace of mind.

Avoiding Costly Mistakes: Improper installs can lead to leaks, water damage, and the need for costly repairs. A plumber’s experience helps avoid these potential issues, saving you money in the long run.

Warranty Considerations: Some manufacturer warranties might become void if it wasn’t performed by a qualified professional. ( fittings)
