Supply-Only Or Supply And Fit? Buying Your Own Bathroom In Derby

There is a moment that decides how a Derby bathroom job goes, and it happens before anyone lifts a tool. It is the moment a pallet lands in the hallway and someone works out whether everything on it is right. Buying your own suite and paying a fitter for labour alone - supply-only - can genuinely save money, and plenty of homeowners across Littleover, Chaddesden and Mickleover do it well. It can also turn a five-day job into a fortnight of waiting for a replacement waste kit. With a mid-range refit in Derby generally landing somewhere between £4,500 and £8,000, and labour making up roughly half of that, the supply decision is worth a proper hour of thought. Here is how the two routes actually differ once you get past the sticker price.

What Supply-Only And Supply-And-Fit Actually Mean

Supply and fit is the single-price version. Your fitter quotes one figure covering the suite, the tiles, the adhesive, the labour and the rubbish, and they own the whole thing from order to handover. Supply-only means you buy the products, they arrive at your house, and the fitter charges for labour and consumables only.

There is a third version worth knowing about, because it is the one that usually works best: a split. You buy the visible things you care about - the vanity, the tiles, the taps - and the fitter supplies the technical items where a wrong choice costs days, like the shower valve, the tray and the waste. Most of our bathroom remodel customers land here without ever calling it that.

Where The Money Really Goes

Retail prices online look unbeatable, and on a like-for-like basis they often are. What is less visible is the trade account behind a fitter’s quote. On the brands a fitter buys week in, week out, discounts of 20 to 40 percent off list are normal, so the figure in their quote is not the showroom price with a margin bolted on. It is closer to what you would pay online, with a margin inside it.

The honest summary is this. On a straightforward suite from a big online retailer during a sale, supply-only often wins by a few hundred pounds. On anything specified - a decent thermostatic valve, a quality enclosure, porcelain rather than ceramic - the gap closes, and on a bad week it inverts, because you paid retail for one item while the fitter would have paid trade for all of them. Our breakdown of full bathroom renovation costs in Derby puts real numbers against each element.

Who Carries The Risk When Something Turns Up Broken

This is the part that rarely gets discussed at the quote stage, and it matters more than the price gap. Sanitaryware is fragile and it travels badly. Every fitter has a story about it. Chipped basins, cracked trays and enclosures with a scuffed frame are routine, not rare, and a fitter who supplies the goods simply reorders and eats the delay on their own account.

On supply-only, the chasing is yours. Your rights are decent - goods have to be as described and of satisfactory quality, and Citizens Advice consumer guidance covers where you stand with a faulty or missing delivery - but rights are not the same as speed. A replacement shower tray on a five-day lead time does not care that your fitter is booked in Belper the following week. Open every box on delivery day, not on day one of the job.

The Bits Nobody Puts In The Basket

Ask any fitter what actually stops a job and it is almost never the bath. It is a £14 part. Bottle traps and the right waste for a countertop basin, a shower arm that suits the ceiling height, concealed cistern frames, tile trim in the right depth, tanking kits, the correct adhesive for a wet wall, isolation valves, silicone in a colour that matches.

Online baskets are built to sell you the headline item, not the eight small components around it. A suite that looks complete on screen arrives without half of them. This is the single biggest reason supply-only jobs overrun, and it is entirely avoidable: send your chosen products to your fitter before you order and ask them to write you a list of everything else the install will need. Any decent fitter will do this in ten minutes.

When Buying Your Own Genuinely Pays Off

Supply-only earns its keep in a few clear situations. If you have very specific taste - a particular vanity, a tile you found in a Derby showroom, a brassware finish nobody stocks - buying it yourself is simply easier than describing it. If you are renovating slowly and have been collecting items in the sales for months, you are already halfway there.

It also suits landlords and anyone doing several bathrooms, where buying four identical suites at once beats any single-job discount. And if your budget is genuinely tight, supply-only lets you control the spend item by item, dropping to a cheaper basin rather than losing the whole job. The trade-off you accept in return is admin and time, and you should go in knowing that.

When Supply And Fit Is Worth Every Penny

Derby’s older housing is where the case flips. In the Victorian and Edwardian terraces around Normanton and Peartree, bathrooms are often in a rear outrigger with solid brick walls, boxed pipework and floors that have moved over a century. Nothing is square, the plaster is rarely flat, and what fits on paper does not always fit in the room.

In those houses a fitter who measures, then orders, is buying you protection from the 1500mm bath that turns out to need 1490mm, or the enclosure that will not sit against a bowed wall. The same applies to anything structural or regulated - moving a soil pipe, altering a hot water system, tanking a wet room - where the product and the method have to match. It is also the route that keeps your comeback in one place, which matters if something goes wrong. Contractor standards from bodies like TrustMark and the Federation of Master Builders are a useful yardstick when you are comparing firms.

How To Make Supply-Only Work Without Losing Weeks

If you have decided to buy your own, the job is winnable with a bit of discipline. Get everything delivered and unboxed a week before the start date, and check each item against the order rather than assuming. Store it somewhere dry and out of the way, not in the bathroom itself.

Order around 10 percent more tile than the measured area, because breakages and cuts are inevitable and a second batch rarely matches the first exactly. Send product links to your fitter before you buy so they can flag anything awkward. Agree in writing who is responsible for what if an item is faulty, and keep every receipt and order number in one place. Get those five things right and supply-only is a perfectly good way to run a bathroom - most of the horror stories come from skipping them, as our guide to bathroom renovation mistakes to avoid in Derby sets out.

Frequently Asked Questions

Is it cheaper to buy your own bathroom suite?

On the sticker price, usually yes - online retailers discount hard and you can catch a sale. Once you add delivery, the parts most people forget to order, and the extra day of labour that missing parts tend to cost, the gap narrows a lot and sometimes disappears. A fitter’s trade discount is often 20 to 40 percent off list on the brands they buy regularly, which is why supply and fit is rarely the rip-off people assume.

Will a bathroom fitter in Derby install a suite I bought myself?

Most will, including us, and it is a normal way to work. What changes is the warranty position. We guarantee our workmanship either way, but if the shower valve you bought fails in a year, that is a claim against the retailer rather than something we replace free. Ask any fitter to put that split in writing before you book, so nobody is guessing later.

What happens if my bathroom delivery is damaged or late?

On supply-only it is your problem to chase, and the clock is unforgiving - a fitter who has held a week for you cannot usually sit idle while a replacement basin comes from a warehouse. Check every box the day it lands, not the morning work starts. On supply and fit, the fitter absorbs that hassle and reorders on their own account.

How far ahead should I order a bathroom suite in Derby?

Have everything in the house and unwrapped at least a week before the start date. Standard white sanitaryware often arrives within days, but shower enclosures, made-to-order vanity units and anything imported can run to four or six weeks, and tiles are frequently the item that stalls a job because the shade you want is out of batch.
