Not every living room has the depth for a full media wall system, and that's exactly the gap a slimline design is built for. Rather than the deep storage and integrated fireplace builds of a full series, a slim media wall focuses on a shallower profile that still gives you a clean, mounted-TV look without eating into the room.
What Makes a Media Wall "Slimline"
The defining feature of a slimline media wall is cabinet depth. Aspin Collins' Serenity Media Wall Series is built specifically around this, a 36cm deep cabinet paired with slat wall panelling either side of the TV, giving the visual impact of a full media wall without the bulk of deeper storage-focused designs.
That shallower depth matters most in smaller living rooms, flats, or rooms where a deep unit would eat noticeably into usable floor space. It's a genuinely different product to the storage-heavy series in the range, this is about the wall reading as clean and architectural, not about maximising cabinet volume.
Available Sizes
The Serenity range currently comes in two cabinet sizes. The smaller option measures 134cm x 44cm x 36cm and suits TVs from 22" up to 55", paired with three slat wall panels either side. The larger option measures 200cm x 44cm x 36cm, suited to TVs from 60" up to 85", paired with four slat wall panels. Both are genuinely DIY-installable, arriving with clear fitting guidance rather than requiring a professional fit, which is part of what keeps this series more accessible than the fireplace-integrated ranges.
Slimline Doesn't Mean Compromising on Finish
A slim profile doesn't mean a stripped-back look. The Serenity series is available in Anthracite and Candela Marble finishes across MDF and Oak Veneer panelling, so you still get a genuine architectural finish, not a budget-looking shortcut. The slat wall panelling either side of the cabinet is what gives the design its wall-to-wall presence, even though the actual cabinet depth stays shallow.
Checking Your TV Actually Fits
Before ordering, it's worth double-checking your TV's dimensions against the stated size range rather than relying on the screen size alone. A 55" TV can vary in bracket width and depth between manufacturers, so if you're right at the edge of a size bracket, it's worth confirming with the actual TV model rather than assuming. Our TV size and layout guide covers how to work out the right size and mounting position for your specific room, which is worth reading alongside this if you haven't settled on a TV size yet.
Is a Slimline Media Wall Cheaper?
Generally yes, and it's one of the main reasons people choose this route. The Serenity series starts from £795, considerably less than the fireplace-integrated or heavier storage series in the range, since you're not paying for the depth of cabinetry, fireplace hardware, or the more complex electrical integration those designs need. If cost is a factor alongside space, our Media Wall Cost UK guide breaks down what you'll actually pay across the full range of media wall types, so you can see where a slimline build sits relative to the rest.
When a Slimline Design Isn't the Right Fit
If you specifically want an integrated electric fireplace, or you need substantial concealed storage for equipment, books, and media beyond the TV itself, a slimline design will likely feel restrictive. The trade-off for the shallower depth is less internal storage volume, so it's worth being honest about how much you actually need to store before committing to the slim route over a fuller series. Our full Media Walls collection covers the deeper, storage-focused and fireplace-integrated series if a slimline build turns out not to be the right fit for your space.
Frequently Asked Questions
1. How deep is a typical slimline media wall?
Aspin Collins' Serenity series comes in at 36cm cabinet depth, considerably shallower than the fuller storage or fireplace-integrated series in the range.
2. Can I fit a slimline media wall myself?
Yes, the Serenity series is specifically designed as a DIY-installable option, arriving with clear fitting guidance for confident home installers.
3. What TV sizes work with a slimline media wall?
The current Serenity range covers 22" to 55" TVs with the smaller cabinet, and 60" to 85" TVs with the larger option, each paired with matching slat wall panelling.
4. Does a slimline media wall still need an electrician?
If you're adding a TV only with no integrated fireplace or lighting, an electrician usually isn't required, but any added electrics should still be checked and fitted by a qualified professional.
5. Can a slimline design be made to a bespoke size?
If the standard sizes don't fit your space exactly, it's worth getting in touch directly, as bespoke sizing can be discussed for a design that suits your room precisely.
6. Is a slimline media wall as sturdy as a full-depth one?
Yes, the shallower depth affects storage capacity rather than structural stability, the cabinet and slat wall panelling are still built to securely support a mounted TV.
