PlumbNation Plumbing Supplies Bathroom Guide

Whether you’re looking to renovate your current bathroom for a new, bright, practical, cutting edge bathroom or you’re looking to create a new bathroom from scratch, you’ll find all you need here from our PlumbNation Plumbing Supplies Bathroom collection. Below you will find our comprehensive Bathroom Guide, which outlines important prerequisites and requirements of a new bathroom that will also hopefully inspire you with new, fresh ideas.

Bathroom Design & Planning Tips:

  • Measure your bathroom - you will need to know the exact dimensions of your bathroom, including the height, width and length.
  • Decide what bathroom pieces you will need - for example do you need a bath, a bath and a shower, a walk in shower, a bidet, etc.? Do you want Bathroom Furniture (built-in cupboards) to conceal all pipework and the toilet cistern? Your choices will normally be influenced by the amount of space you have and your budget. 
  • Check that your boiler & cylinder is suitable - a shower with a high flow rate and a small supply of water will cause your time in the shower to be very short. Power Showers & Shower Pumps are not suitable for use with a Combi Boiler or an Unvented Cylinder. Taps are also limited by the flow rate of your mains water supply. If you are ever unsure you should always consult your professional installation team or the relevant manufacturers.
  • Soil Stack & Waste Position - Most properties only have one Soil Stack, this is a large 4 inch pipe that is either found on an outside wall of the property, or concealed within the internal walls. Is your Soil Stack positioned near your planned new bathroom or the planned new position of your toilet? If not, you should consider installing a Macerator Pump. This will enable you to position your toilet anywhere in the property by reducing the waste and pumping it to the soil stack. Most Macerators also include waste water connections for baths, showers, and basins.
  • What kind of Shower to install - Mixer Shower, Electric Shower, Digital Shower or Power Shower? Mixer Showers require a hot & cold water supply. Electric Showers only require a cold water supply but also require specific electrical cable and must be installed by a qualified electrician. Power Showers are not suitable for use with Combi Boilers or Unvented Cylinders. Please see our Shower Guide below for full details.
  • Plan the lighting of your bathroom carefully - a perfectly lit bathroom can transform the design, so be sure to fill your bathroom with either natural or artificial light to set the right ambiance. Any electrical work in your bathroom must be carried out by a registered electrician.
  • Decide upon the décor and theme of your bathroom - once all of the technicalities have been agreed upon you can start having fun with the bathroom’s aesthetics. A good starting point is to decide upon a theme. For example a bright, modern contemporary style to awaken and inspire your senses the moment you enter the room may be you’re your ideal bathroom, or perhaps a calm, traditional rustic bathroom is all you need to start your day. The possibilities for your new bathroom are endless, so don’t rush into it, ponder your perfect bathroom and get it right the first time.
  • Read installation instructions provided by the manufacturer - it may seem obvious but many of us are guilty of ripping open the packaging and acting before thinking. Not everything for the bathroom will require a professional installation however if you are ever in doubt be sure to contact the manufacturer directly.
  • Use registered professionals for important bathroom installations - perhaps the most important point of all. You don’t want to spend good money on a top end bathroom suite only to have the installation botched by a couple of cowboys. Once your perfect bathroom has been installed correctly it will last for generations if cared for properly, meaning money well spent.


All Toilets consist of two parts - a Toilet Pan & a Toilet Cistern. The Toilet Pan is the lower piece that the Toilet Seat mounts to. The Toilet Cistern is the higher piece that contains the water to allow the Toilet to flush. There are several different configurations of Toilet Pans & Cisterns:.

  • Close Coupled Toilets - The most common kind of modern Toilet. The Cistern mounts directly onto the Pan and forms part of the design of the complete Toilet. Most Close Coupled Toilets have a push button operated flush mounted on the top of the cistern. 
  • Back-to-Wall Toilets - Used in modern designer bathrooms. The Cistern is concealed behind a tiled wall or within Bathroom furniture. A plastic 'Flush-pipe' is used to connect the Cistern to the Pan (usually included with the Cistern). A separate 'Flush Plate/Button' is required to operate the flush mechanism of the Cistern (usually supplied separately). 
  • Wall Hung Toilets - Uses the same Cistern configuration as a Back-to-Wall toilet, but the Toilet Pan is lifted of the floor and mounted to the wall. This look is achieved by mounting the Pan to a reinforced frame concealed behind the wall.
  • Low Level Toilets - Although they are called 'Low Level', the Cistern actually mounts higher than the commonly used Close Coupled Toilet. The Pan and Cistern are both exposed, but the Cistern is mounted slightly above the Pan and is connected via an exposed 'Flush Pipe' (usually supplied with the Cistern). Low Level Toilets are usually found in older properties, or newer properties trying to achieve a traditional style. Most Low Level Toilets have a Lever operated flush handle, as opposed to the modern 'Push Button' Cistern.
  • High Level Toilets - Uses the same Cistern configuration as a Low Level Toilet, but the Toilet Cistern is mounted much higher. Usually found in schools or commercial properties, a High Level Cistern flush is operated by an extended chain pull. High Level Toilets are now found in high end traditionally styled bathrooms.


  • Basins & Pedestals - The most commonly used type of Bathroom basin requires a separate Pedestal. A Pedestal is mounted below the Basin and has three uses - to give the basin extra support, to conceal pipe-work, and to add to the design of the complete Basin Unit. Half or Semi Pedestals are also available, but they do not offer any extra support to the Basin and are for design purposes only.
  • Cloakroom Basins - Often used in en-suite bathrooms or where space is at a premium, Cloakroom Basin is just a name given to a smaller size Basin, usually 450mm or less. Most Cloakroom Basins are wall mounted with no pedestal, so require an exposed chrome Bottle Trap. 
  • Countertop Basins - Used in modern designer Bathrooms, a Countertop Basin is designed to sit on top of a work surface, with no wall mounting required. There are three different ways to mount a Countertop Basin - 1. On top of the work surface (this usually requires a tall extended Mixer Tap to reach into the Basin), 2. Recessed into the work surface (like a Kitchen Sink), or 3. Under-mounted - fixed to the underneath of the work surface, creating a sleek seamless look.
  • Semi Recessed Basins - Designed to sit on the edge of a work surface with the front of the Basin exposed and the rear recessed into a worktop. These are commonly used with built-in Bathroom Furniture and Bathroom Cupboards.


The PlumbNation Plumbing Supplies Shower collection has been thoughtfully handpicked to offer quality showering products for all manner of Bathroom designs, layouts and requirements. In this section you will find Power Showers, Mixer Showers, Electric Showers, and Digital Mixer Showers.

  • Electric Showers - An Electric Shower is a very suitable option for your Bathroom when you are in need of classic, economic Shower to simply get the job done. They are simple to install and will always provide you with instant hot water (no need to heat your Hot Water Cylinder or use your Combi Boiler). Electric Showers only require a cold water supply and an electrical supply. Different sized kW Showers will require different sized supply Cable. Check with your installer before purchase. An Electric Shower must be installed by a qualified electrician. 
  • Mixer Showers - Require a cold water supply and a hot water supply from either a Hot Water Cylinder or Combination Boiler. Dependant on your hot water supply, they can offer much greater water pressure then an Electric Shower, but they will require your Boiler to be switched on. There are two main types of Mixer Shower - Concealed Valves and Exposed Valves. Concealed Valves are designed to be recessed in a tiled wall, concealing all the pipe-work and most of the Valve. An Exposed Valves is mounted on top of the tiles, exposing all the pipe-work and connections. Exposed Valves are commonly used on solid outside walls, and Concealed Valves can only be used on internal timber walls. 
  • Digital Mixer Showers - A similar design to a standard Mixer Shower - both hot & cold water supplies required, but with added technical features. Digital Mixer Showers contain a processing unit, a digital programmer, and a shower head. A hot & cold water supply is feed to the processing unit, the digital programmer allows temperature control, then the perfect temperature water is delivered to the shower head. The processing unit and digital programmer can be mounted away from the shower offering great flexibility and the option to control your shower from your bedside. Digital Mixer Showers are available in two options; Pumped - for use with Open Vented Hot water Cylinders (traditional system with a header tank in your loft), or Un-pumped/High Pressure - for use with Combination Boilers and Unvented Cylinders. 
  • Power Showers - A pumped version of an Electric Shower. Can offer much higher flow rates than a standard Electric Shower by pumping your cold water supply. Requires a cold water supply and an electrical supply. Only suitable for use on Open Vented Systems with a cold water storage tank. Not suitable for use with Combination Boilers or Unvented Systems

Shower Enclosures

  • Pivot Door Shower Enclosures - The most common type of modern Shower Cubicle. A simple design that features a single door that pivots on a single set of hinges. Very easy to keep clean & maintain, and available in a wide range of sizes. 
  • Bi Fold Door Shower Enclosures - Ideal for use where space is at a premium, a Bi-fold Shower Cubicle folds inwards into the Shower Cubicle requiring no clearance outside of the Cubicle area.
  • Sliding Door Shower Enclosures - Mostly found on larger Shower Cubicles of 1000mm length or more. Sliding Door Shower Cubicles require no clearance outside of the Cubicle area and offer a very generous showering area. 
  • Quadrant Shower Enclosures - Designed for use in corner spaces, they are a luxury space saving option. Most Quadrant Shower Cubicles feature single or double sliding doors and require no side panels.  
  • Pentangle Shower Enclosures - Very similar to Quadrant Shower Enclosures, but feature a straight pivot door entry. Designed for use in corner spaces and an ideal space saving option.
  • Walk-in Shower Enclosures - The ultimate in designer bathroom luxury. Walk-in Shower Cubicles have no moving parts and offer a sleek seamless look. Most Walk-in Enclosures offer a very generous showering space with splash areas so do not require hinged doors.

Bath installation guide tips: First, measure the bath, piping and bath waste areas and mark them out. Now attach the feet assembly to the bath, then fit the taps, waste and overflow before positioning the bath. Once everything is in place, use a spirit level to determine whether or not the bath is level. Create a waterproof seal between the bath and the adjacent walls where required.

Water Tap Pressure

Water pressure will play a pivotal role in deciding which tap to buy. Many households in the UK have low water pressure (without any additional pressure boosting systems installed). Typically, water is fed through to the water taps via a gravity fed system, such as a tank in the loft. However if you have a combi boiler or an Unvented Hot Water Cylinder installed then you can make full use of the high mains pressure available, and a wider choice of water tap options.

Check the current pressure of the hot water system, water pressure can be measured in three common units, bar, psi and Head (m).

1 bar = 14.5 psi = 10 metres Head

For example if the vertical distance from the tank to the water tap is 5m then there will be approximately 0.5 bar maximum pressure available. However if the pipes make several bends or have long horizontal runs then the available water pressure will be reduced.

Each water tap will state its minimum requirement for water pressure (for example 1 bar). You can normally find this information within the product information or brochure however if in doubt we recommend that you contact the manufacturer of the tap or tap accessories directly.
