Choosing a new shower may seem simple at first, but there’s more to it than picking out a great-looking unit. A good shower should match your home’s plumbing system, deliver reliable performance and suit the needs of everyone using it. Whether it’s a complete bathroom upgrade or just a long-overdue replacement, a little preparation can make a big difference.
At Manchester Plumbing and Heating, we help homeowners in Sale get it right the first time. Here’s what to consider before making your choice.
Shower Types
Not all showers work in the same way, and understanding the differences can help you avoid frustration later on. The main types available in the UK include electric, mixer, power and digital showers.
Electric showers heat cold mains water on demand, so they work independently of your boiler. They’re ideal for busy households, guest bathrooms or homes with limited hot water availability. Because they’re not affected by stored hot water levels, they can be used even if the heating is off. However, water pressure is directly tied to the mains supply, which can feel underwhelming in some properties.
Mixer showers draw from both hot and cold water supplies, combining them to reach the desired temperature. These are most effective in homes with a reliable hot water system, such as a combi boiler or unvented cylinder. They tend to offer stronger flow than electric models and are available in both manual and thermostatic versions.
Power showers are essentially mixer showers with a built-in pump, designed to boost flow where water pressure is low. They’re commonly used with gravity-fed systems and can dramatically improve the showering experience in older homes. However, they are not suitable for homes with combi boilers or high-pressure systems.
Digital showers are the most modern option, offering precise control via remote panels, smart devices or even voice activation. They’re popular in new bathrooms for their clean design and ease of use. Some digital models are compatible with all plumbing systems, while others need a specific setup, so it’s essential to check compatibility before purchasing.
The right choice depends on your property’s setup and what matters most: whether that’s energy efficiency, strong flow, ease of installation, or smart technology.
Water Systems
Your existing water system is one of the most important factors when choosing a new shower. In the UK, homes typically use one of three types: gravity-fed, combi boiler, or unvented (pressurised) systems. Each type behaves differently, especially in terms of pressure, flow, and temperature consistency.
A gravity-fed system is the most traditional setup, usually found in older properties. It consists of a cold water tank in the loft and a hot water cylinder elsewhere, often in an airing cupboard. These systems usually produce low water pressure, particularly in upstairs bathrooms. In such cases, a power shower or a booster pump may be necessary to achieve a decent flow.
A combi boiler system heats water on demand, drawing directly from the mains without storing it in a cylinder. It’s space-saving and energy-efficient, but water pressure depends on the mains supply, and flow can drop if multiple outlets are used at once. Mixer or digital showers tend to work well with combi systems, provided they’re compatible.
An unvented system, also known as a pressurised or sealed system, stores hot water in a cylinder and delivers it at mains pressure. This gives you excellent flow and temperature stability, making it suitable for high-spec showers, including rainfall and digital setups. It’s a flexible system that works with most modern shower types, though installation tends to cost a bit more upfront.
If you’re unsure about the type of system you have, a quick visit from your local plumber can help clarify it and ensure you choose a shower that won’t cause pressure or temperature issues later.
Water Pressure
Water pressure is one of the most overlooked but critical parts of a successful shower installation. It directly affects performance, especially for showers with large heads or multiple outlets—poor pressure results in weak flow and a disappointing showering experience.
In general terms, gravity-fed systems have low pressure by default and may need pumps to boost performance. Combi and unvented systems usually offer better pressure, but it’s still worth testing. A shower that requires a minimum pressure of 1.5 bar won’t perform well if your system can only deliver 0.8 bar.
Flow rate is another key measurement, representing the volume of water delivered per minute, typically measured in litres. A good shower should offer around 10 to 12 litres per minute as a minimum. Some rainfall or high-output showers may require 15 litres or more. If your flow rate falls below this, you may need to reconsider the model or look into system improvements.
At Manchester Plumbing and Heating, we regularly test the flow and pressure in homes across Sale and recommend showers that will deliver the best performance for the existing system. If pressure is too low, we can advise on pumps, filters or upgrades to bring it up to scratch.
Controls and Safety
Shower controls significantly impact both comfort and safety. Manual showers are affordable and straightforward, but they offer less precise temperature control. Thermostatic showers, on the other hand, maintain a steady temperature even when water usage elsewhere in the home changes. This makes them an excellent choice for families and households with shared bathrooms.
Some models also include safety cut-offs to prevent scalding in the event of a cold water failure, a helpful feature in homes with children or elderly relatives.
Digital controls are gaining popularity due to their sleek design and user-friendly operation. They enable custom temperature presets, remote activation, and, in some cases, app-based control. Although they may be more expensive upfront, they can be a wise long-term investment.
Design and Layout
A shower should look good, feel comfortable to use and be built to last. You’ll want to think about layout, especially in small or awkward bathrooms. Wall-mounted showers with concealed pipework offer a modern, clutter-free look. Exposed models are easier to maintain and often quicker to install.
Choose fittings that match your bathroom’s finish and avoid overly cheap materials. Plastic handles and chrome-plated fittings tend to wear out quickly, while brass and stainless steel offer greater durability.
Installation Help
Even the best shower can underperform if it’s installed without proper planning. That’s why working with an experienced local plumber makes all the difference. A correct assessment will confirm compatibility, highlight any pressure or plumbing issues, and ensure your new shower is fitted neatly and safely.
At Manchester Plumbing and Heating, we take care of the entire process, from helping you choose the right model to final installation and aftercare. We’re based in Sale and provide reliable service throughout the area, with transparent pricing and honest advice.
Getting it Finished
Once the proper shower is chosen and the plumbing is checked, installation is often straightforward. In most cases, the work can be completed in a single day. However, older systems may require additional pipework, pumps or valves to meet modern shower requirements. We’ll always discuss the options with you before starting, so there are no surprises.
