Maximising Space: The Transformation of an Understairs Nook into a Stylish Combined Toilet and Washbasin


In the realm of home design, making the most of every square inch is a challenge many homeowners face. However, creative solutions abound, and one such innovation involves transforming an often-neglected space under the stairs into a functional and stylish combined toilet with a built-in washbasin. This article will take you through the journey from design concept to completion, highlighting the steps taken to conceal pipework, install new lighting, incorporate a designer radiator, and achieve a modern, practical finish.

Design Concept:

The first step in this transformation was to conceptualise a design that seamlessly integrated a toilet and washbasin into the space under the stairs. The goal was to create a functional and aesthetically pleasing area that maximised the use of the available space. The design took into consideration the need for concealed pipework, sufficient lighting, and a modern aesthetic that would complement the overall decor of the home.

Concealed Pipework:

One of the challenges in combining a toilet and washbasin is concealing the necessary pipework. To address this, the design incorporated clever solutions such as recessed wall spaces and custom work to hide the plumbing. This not only ensured a clean and streamlined look but also maximised the available space.

New Lighting:

Effective lighting is crucial in any space, and the underspace of the stairs is no exception. The design included the installation of modern and energy-efficient lighting fixtures to illuminate the area effectively. Recessed LED lighting strategically placed to create a bright yet ambient atmosphere, enhancing both the functionality and visual appeal of the combined toilet and washbasin.

Designer Radiator:

To make the space not only functional but also comfortable, a designer radiator was introduced. This not only served the practical purpose of heating the area efficiently but also added a touch of elegance to the overall design. The choice of a designer radiator was carefully made to complement the modern aesthetic and provide an additional focal point in the space.

Full Decoration:

The transformation extended beyond the functional elements to include a full decorative overhaul. A bright colour scheme and quality materials were chosen to create a cohesive and visually appealing finish.


The conversion of an underspace beneath the stairs into a combined toilet and washbasin is a testament to the innovative use of available space in home design. From concealing pipework to incorporating new lighting, a designer radiator, and full decoration, this project showcases how a thoughtful design concept can result in a practical and stylish addition to the home. The end result is a combined toilet and washbasin that not only maximises space but also contributes to the overall modern and elegant finish of the residence.
