Custom Size uPVC Bathroom Windows
Bathrooms are brutal environments for standard windows. Constant steam, high humidity, and fluctuating temperatures will quickly rot wooden frames and corrode cheap metals. More importantly, you need a window that vents out damp air without compromising your privacy.
Our uPVC bathroom windows are engineered specifically for high-moisture zones. Featuring multi-chambered uPVC profiles that will never warp, peel, or rot, these windows are built to last. Whether you are replacing a drafty old unit or fitting out a new build, we manufacture custom size uPVC bathroom windows to your exact rough opening dimensions.
Why Choose Our Bathroom Windows?
- Total Privacy, Maximum Light: We offer multiple levels of frosted glass uPVC bathroom windows, ranging from light distortion (Level 3) to complete block-out obscure glass (Level 5). You get natural sunlight without the need for damp, mold-prone blinds.
- Smart Ventilation: A hot shower creates massive amounts of steam. Our uPVC bathroom window models allow you to tilt the top of the sash inward to let steam escape without letting rain in, or swing the window fully open for rapid air clearing.
- Built-in Moisture Control: To comply with modern building codes and stop black mold before it starts, every unit can be upgraded to a uPVC bathroom window with a trickle vent, ensuring background airflow even when the window is securely locked.
- Modern Aesthetics: Gone are the days of cheap-looking plastic. We offer sleek white, matte black, and grey uPVC bathroom windows with obscure glass to match contemporary tile and fixture designs.

FAQ
Q: How do I measure for custom size uPVC bathroom windows?
A: Always measure the width and height of the brickwork opening (the outside hole) in three places: top, middle, and bottom. Take the smallest measurement for both width and height, and deduct 10mm. This gives you your manufacturing size and allows room for leveling and sealant.
Q: Are obscure glass uPVC bathroom window prices higher than clear glass?
A: There is a slight premium for frosted or obscure glass compared to standard clear double glazing due to the texturing process, but it is minimal. The exact cost depends on the privacy pattern you choose. Contact us for a precise quote based on your dimensions.
Q: Does the frosted glass affect the thermal efficiency (U-value) of the window?
A: No. The frosted or obscure texture is applied to the inside face of the outer pane of glass. The sealed double-glazed unit still contains argon gas and a warm-edge spacer bar, meaning you get the exact same A-rated thermal efficiency as a clear window.
Q: Why should I choose a tilt and turn window for my bathroom?
A: Bathrooms need constant airflow to prevent dampness. A tilt-and-turn window is ideal because the "tilt" function opens the top of the window slightly. This draws damp air out and lets fresh air in, while keeping the window locked against intruders and preventing rain from entering.
Q: Do I legally need a uPVC bathroom window with a trickle vent?
A: If you are replacing an existing window that currently has a trickle vent, building regulations generally require the new window to have one too. If you are building an extension or a new home, trickle vents are almost always mandatory to ensure proper background ventilation and prevent mold.
Q: I want to match my modern decor. Can I get a grey uPVC bathroom window with obscure glass?
A: Absolutely. Anthracite Grey (inside and out, or Grey outside/White inside) is one of our most popular finishes. We apply a highly durable, woodgrain or smooth foil to the uPVC that resists scratching and fading, perfectly complementing modern bathroom tiles.
Q: If the locking mechanism fails in the future, is the uPVC bathroom window lock easy to replace?
A: Yes. We use standard, high-quality espagnolette multi-point locks. If a handle or lock ever becomes stiff or damaged due to years of bathroom humidity, the hardware can be easily unscrewed and swapped out without needing to replace the whole window frame.
