Thetford has launched three new sink bowls for caravans and motorhomes: the SBL2410, SBL2500 and SBL2510. Vehicle builders can fit them now. They reach the aftermarket for the 2027 season.

The release talks about contemporary design and memorable moments on the road. Strip that out and two facts are left. Builders asked for these sinks. And Thetford is selling them on price.

That second point is the story.

What Thetford Has Actually Launched

Here’s what the release confirms:

  • Three model codes: SBL2410, SBL2500 and SBL2510.
  • Developed after requests from vehicle manufacturers, which Thetford doesn’t name.
  • Available for factory fitting now, and in the aftermarket from season 2027.
  • Pitched at what Thetford calls a “highly competitive price point”, which it credits to leaner production.

Here’s what it doesn’t say. No dimensions, cut-out sizes or bowl depths. No trade or retail prices. Thetford claims early take-up by leading manufacturers, but names none.

At the time of writing, the new bowls don’t appear on Thetford’s European sinks and bowls page.

Its current round spun bowl, the SBL22 and SBL23, first went on sale in 2008. The new codes follow the same SBL naming, so they look like the next generation of that line. Thetford hasn’t said whether they replace it.

Why a Sink Launch Matters More Than It Looks

A sink is about as plain as a component gets. Nobody walks onto a forecourt asking about bowl depth.

That’s why the pitch is telling. When a supplier of Thetford’s size leads with price on a commodity part, and says builders asked for it, the signal is clear: manufacturers are looking hard at the cost of everything behind the cupboard doors.

It fits the rest of Thetford’s 2027 kitchen line-up. The matte 902 induction hob keeps the same cut-out as the model it replaces, so builders can swap it in without redesigning the furniture.

The sinks follow the same logic. A cheaper part that drops into a modern kitchen without fuss.

Nothing wrong with that. A builder who saves on the sink can hold a price point or spend the money where buyers notice it.

The test is whether the quality holds up after a few seasons of heavy pans and hard water. Thetford says its quality standards are unchanged. Nobody outside Thetford has tested that yet.

What This Means for UK Dealers

You won’t sell a single extra van because of a sink. You can make money from what happens after the sale. Three things to do before the 2027 season:

  1. Ask your manufacturer reps which 2027 models carry an SBL bowl. Your workshop and parts counter need the part number before the first customer chips one.
  2. Get the spec sheet before you stock it. Ask Thetford or your distributor for dimensions, cut-outs and trade price. If the cut-out matches older Thetford bowls, this becomes a straight swap for owners with a stained or damaged sink. If it doesn’t, it’s a refit job, and you should price it that way.
  3. Treat it as a parts and workshop line, not a showroom feature. For owners of older vans, a lower-priced replacement bowl is an easier yes than a full kitchen refit. That’s a counter sale plus a workshop hour. Our piece on caravan spares as a hidden goldmine explains why small lines like this add up.

For buyers on the forecourt, nothing changes. The benefit to owners only becomes real once aftermarket prices are known.

The Bigger Signal

Thetford doesn’t need to compete on price. It sits at the top of the European market in sanitation and kitchen kit, and describes itself as the world’s leading supplier in its field.

So when it leads a launch with cost, take note. Likely next: more “same quality, lower cost” launches across fridges, hobs and taps as builders guard their margins, and smaller suppliers pushed to match.

Do you know what’s inside the cupboards of the vans you’ll sell next year, and what each part costs to replace? If not, start with the sink.
