There's a reason the toilet seat riser is one of the most widely recommended pieces of accessible bathroom equipment in the UK. It solves a very specific, very common problem: the difficulty of lowering onto and rising from a standard-height toilet without requiring any building work, plumbing or significant expense. For the right person, it can restore independence to one of the most fundamental daily routines almost immediately.
Wash-Able's 50mm toilet seat riser is designed precisely with that goal in mind. If you or someone you care for is finding the bathroom increasingly difficult to manage, one of the most effective first steps you can take is to raise your toilet height - and 50mm, or roughly two inches, is the increment that makes the most meaningful difference for the widest range of people.
This guide explains exactly what the product is, how it works, who it's best suited to and what to consider when deciding whether it's the right solution for your situation.
What is a 50mm Toilet Seat Riser?
A toilet seat riser is a raised platform that fits directly onto your existing toilet pan, increasing the height of the seating surface. Wash-Able's riser adds 50mm to the height of a standard toilet, bringing it closer to the height of a typical chair.
Most standard UK toilet pans sit at around 400mm from the floor to the top of the seat. Adding 50mm brings this to approximately 450mm, which is roughly equivalent to the height of a comfortable dining or kitchen chair. For many people, this relatively modest adjustment makes an enormous practical difference to the ease and safety of sitting down and standing up.
The riser is made from high-density polyethene (HDPE), a robust, hygienic and easy-to-clean material that is well-suited to a bathroom environment. It includes a built-in splash guard for hygiene, and is designed to fit securely onto most standard UK toilet pans without any tools or fixings.
How Does It Work?
The mechanism is straightforward: the riser sits atop the toilet pan rim, beneath the toilet seat. It effectively acts as a spacer between the pan and the seat, raising the overall seating height by 50mm.
There are no moving parts, no power supply and no mechanical components. The riser is a passive device; it simply changes the toilet's geometry to make sitting and standing movements less demanding on the body.
Installation takes a matter of minutes. The riser is placed onto the pan, the toilet seat is repositioned on top, and it is ready to use. No plumber, no DIY experience and no tools are required in most cases.
Who Is the 50mm Toilet Seat Riser For?
The 50mm riser is suitable for a broad range of people. It is not a specialist clinical product; it is a practical, everyday solution that addresses one of the most common physical challenges in the home. Here are the people most likely to benefit:
People Recovering From Hip or Knee Surgery
Following a hip or knee replacement, one of the first things a physiotherapist or occupational therapist will recommend is raising the toilet height. Bending the hip or knee beyond a certain angle in the early weeks of recovery can risk dislocation or damage to the surgical site. A 50mm riser reduces the depth of the bend required, keeping the movement within a safe range during rehabilitation.
For post-surgical recovery, a riser is often a temporary measure, used for the weeks or months of rehabilitation before full mobility is restored. Because it requires no installation and can be removed just as easily, it is ideal for this purpose.
People With Arthritis
Arthritis (particularly osteoarthritis affecting the hips, knees, or lower back) makes deep bending painful and, in some cases, dangerous. The effort of lowering onto a low toilet and pushing up to standing puts significant stress on affected joints, often at the start and end of the day when stiffness is at its worst.
Raising the toilet height reduces the range of motion required and decreases the load on the joints during the transition. Many people with arthritis report that a toilet seat riser is one of the most effective home adaptations they have made, despite its simplicity.
Older Adults With Reduced Leg Strength
As we age, the muscles responsible for controlling the lowering and rising movement (primarily the quadriceps and gluteal muscles) naturally weaken. This makes the act of sitting down onto a low surface and pushing up from it increasingly effortful and, over time, risky.
A higher seating surface requires less muscular force to lower onto and rise from, because the range of motion is shorter. A 50mm riser can meaningfully reduce the effort required to use the toilet for older adults who are beginning to find the movement difficult but are otherwise managing independently.
People Managing Bladder Urgency
As discussed in our earlier guide to bladder weakness and menopause, urgency incontinence places a premium on speed in the bathroom. A higher toilet seat reduces the time and effort needed to sit down, which can make a significant difference during an urgency episode. A riser is one of the most practical and immediate adaptations available for anyone managing this condition.
Taller Individuals
Standard toilet heights are designed around average body proportions, so taller individuals, particularly those over 6 feet, often find standard toilets uncomfortable, even without mobility challenges. A 50mm riser brings the seating height closer to the proportions of a taller frame, reducing the awkward, low-down sitting position that can cause knee and lower back discomfort over time.
People Awaiting a More Significant Adaptation
For anyone on an occupational therapy waiting list, or waiting for a Disabled Facilities Grant assessment, or simply taking time to decide on a longer-term solution, a toilet seat riser provides an immediate, affordable interim measure. It can be in place within hours of ordering, providing meaningful support while more comprehensive plans are made.
The Riser With Support Rails: An Important Upgrade
Wash-Able's 50mm toilet seat riser is also available with integrated steel support rails on either side of the seat. This version addresses a limitation of the standard riser: it raises the seat but provides nothing to hold onto.
For users who need both height and lateral stability, the support rail version is a significant improvement. The rails provide something firm to grip when lowering and rising, which:
- Reduces the muscular effort required from the legs by allowing the arms to share the load
- Improves balance and confidence, particularly for people who feel unsteady during the transition
- Slows the descent in a controlled way, which is important for anyone with joint pain or post-surgical restrictions
The rails are fixed to the riser unit itself rather than to the wall, so no wall fixings are required, and the whole unit can be moved or removed without leaving any marks or damage. This makes it particularly suitable for rented accommodation.
The Riser and Washloo Smart Toilet Combination
For those who want to combine height assistance with the hygiene and independence benefits of a wash and dry toilet, Wash-Able also offers the 50mm riser in combination with the Washloo Smart Toilet Seat, either with or without a new rimless ceramic pan.
This combination means you don't have to choose between a height adaptation and a smart toilet function. The riser lifts the seated position to a more comfortable height, while the Washloo Smart Toilet Seat provides warm water washing, warm air drying, and the other features that reduce the need to reach, twist, or rely on toilet paper - a combination that can be particularly valuable for people with limited upper limb mobility or dexterity.
What the 50mm Riser Does Not Do
It is equally important to be clear about the limitations of a toilet seat riser, so that expectations are realistic and the right product is chosen for the right situation.
It does not provide mechanical lifting assistance. A riser changes the height of the seat; it does not actively assist the user to rise. If the main challenge is the muscular effort of pushing up to standing, rather than the depth of the bend, a lifting toilet seat or a rise & fall WC may be more appropriate.
It does not adjust. The height increase is fixed at 50mm. If different users of the same toilet have different needs, or if needs are likely to change significantly over time, a rise-and-fall WC (which adjusts at the touch of a button across a wide range of heights) offers greater long-term flexibility.
It requires reasonable existing strength and balance. A riser works best for people who can sit and stand independently with some difficulty, rather than those who cannot manage the transition at all without significant assistance.
Frequently Asked Questions
Will a 50mm toilet seat riser fit my toilet? Wash-Able's 50mm riser is designed to fit most standard UK toilet pans. If you are unsure, Wash-Able's team can advise based on your existing toilet specifications.
Is the riser hygienic? Yes. The HDPE material is non-porous, easy to wipe clean, and resistant to bacteria. The built-in splash guard provides additional protection. The riser can be removed for thorough cleaning as needed.
Can I use my existing toilet seat with the riser? In most cases, yes. The riser sits between the pan and the toilet seat, so your existing seat can be repositioned on top. Some toilet seat designs may not sit flush depending on their fixing mechanism; this is worth checking before ordering.
Is the riser suitable for bariatric use? Wash-Able's standard riser is suitable for most users. For those who require a higher weight-rated product, it is worth contacting Wash-Able directly to discuss the most appropriate option.
Can I take the riser with me if I go on holiday or visit family? Yes. Because it requires no installation, the riser is fully portable. It can be placed in a bag and used in any bathroom, which many users find valuable for maintaining independence away from home.
