How to Design a Bathroom: A Complete Guide

When it comes to refreshing a bathroom, the vanity unit often takes centre stage. It is not only where the basin sits, but also the feature that ties style, storage and practicality together. 

But here’s the challenge: how do you pick the right one? And with so many sizes, finishes and storage options to choose from, it can feel very overwhelming. The good news is that a little planning below will make the process much simpler for you.  

In this guide, we’ll look at the essentials, from just measuring the space you have to work with, to picking a style and aesthetic that matches your home, so you can select a unit that works beautifully for your bathroom. 

Layout and Space Planning

Assess available space and traffic flow

Start by measuring every part of the room including doors windows and alcoves. Remember to think about how people move around the space because a clear path makes the bathroom feel more open. Good planning prevents tight corners and ensures each fixture feels comfortable to use. 

Zoning wet vs dry areas

Bathrooms work best when wet and dry zones are clearly defined. Wet zones include showers and baths while dry areas include basins toilets and storage. Keeping these zones organised helps with cleaning and protects surfaces from unnecessary water. A well-placed screen can keep water controlled without blocking the flow of the room. 

Plumbing drainage and fixture placement

Fixture placement is influenced by the location of existing plumbing, drainage requirements and building regulations. Working with a licensed plumber ensures that toilets, showers and basins are positioned optimally and that drainage systems function properly. Planning for these considerations early in the project helps avoid delays and ensures a smooth installation process. 

Fixtures and Fittings Selection

Choosing bathtubs showers and enclosures

Your choice of bath or shower depends on the room size and your lifestyle. Walk in showers create a modern spacious feel while traditional baths offer comfort and relaxation. Shower enclosures come in many styles so be sure to pick one that suits your layout and cleaning preferences. 

Toilet and basin types

Wall hung toilets create a clean floating look that makes the room feel larger. Floor mounted toilets offer a classic style. Basins come in countertop inset or wall mounted designs and each option influences the overall feel of the bathroom. Consider both style and ease of cleaning when choosing. 

Tapware mixers and shower systems

Tapware can bring the whole look together, so choose styles and finishes that complement the rest of the room. Some systems have pressure requirements so check compatibility with your home. Concealed systems offer a sleek finish while exposed systems provide easier access for maintenance. 

Materials Finishes and Flooring

Waterproofing and underlayment essentials

A reliable waterproof base is essential in any bathroom. Underlayment materials like cement board and waterproof membranes create a secure surface for tiles or panels. Pay extra attention to showers and bath surrounds where water contact is constant. Good waterproofing protects your bathroom for years to come. 

Tile stone and alternative flooring choices

Ceramic tiles natural stone and modern vinyl flooring are all popular choices in recent times. But each material has its own level of durability and slip resistance. Stone may require sealing, then there’s the tiles that need more grout cleaning, while vinyl offers easier upkeep. And if you want underfloor heating, make sure to check compatibility before choosing the right material for your needs. 

Wall finishes grout and long-term durability

Tiles offer a traditional choice, but wall panels as well as moisture resistant paint can create a smooth modern finish. High quality grout reduces staining and improves the long-term look of your walls. When selecting finishes think about both appearance and how much maintenance you want in the future. 

Lighting Ventilation and Electrical

Layered lighting

Bathrooms benefit from several types of lighting. Ambient lighting provides general brightness while task lighting supports activities such as; shaving or applying makeup. Accent lighting creates a softer atmosphere for relaxing moments. Warm tones feel soothing while cooler lights suit task areas. 

Ventilation extraction and moisture control

Proper ventilation is key to a comfortable, long-lasting bathroom. A well-designed extractor fan helps reduce condensation and prevent mould. A professional bathroom fitter will ensure the fan is the right size and positioned for optimal performance, keeping your bathroom fresh and low maintenance. 

Safe electrical placement and IP ratings

Bathrooms have specific safety zones that guide where lights and appliances can be placed. IP ratings show how well a fixture resists moisture. Always choose lighting that matches the zone it will be installed in and use a qualified electrician for any electrical work to ensure full safety. 

Storage Accessibility and Styling

Built in vs freestanding storage solutions

Storage is essential for a tidy and comfortable bathroom. Fitted cabinets create a seamless look while freestanding units let you change the layout more easily. Moisture resistant materials keep your storage looking good over time. 

Universal design and accessibility features

Accessibility can be built into any bathroom design. Features like slip resistant flooring wider doorways and easy to reach fixtures improve comfort for all ages. These design elements can blend seamlessly with modern styling. 

Colour palettes accessories and finishing touches

Colour has a big impact on atmosphere. Neutral tones give a calm spa like feel while bold colours add personality. Mirrors, plants, towels and accessories complete the look and tie the design together.
