Cheapest place to buy plumbing supplies in South Africa (2026 price comparison)
6 June 2026 · Plumbers On Duty
Every plumber and homeowner in South Africa eventually asks the same question: where do I get plumbing supplies for the lowest price without ending up with rubbish that fails inspection? We pulled live online prices from the big national retailers, Cashbuild, Builders Warehouse, Build It, Brights Hardware, Leroy Merlin, Makro, Chamberlain and BUCO, on a basket of items that show up in 90% of repair jobs, then worked out who actually wins on each line and on the trolley as a whole.
All prices are VAT inclusive, in ZAR, and were captured in early 2026. They will drift a few rand week to week, but the relative ranking between stores is very stable, that is the part that matters when you are deciding where to drive.
The basket we priced
We chose items that 95% of South African homes need at some point:
- 15 mm Class 0 copper pipe, 5.5 m length , the standard hot/cold water pipe
- 40 mm PVC waste pipe, 6 m length , basin and bath waste, vent stacks
- PTFE (plumbers') tape, 12 mm x 10 m , thread sealant
- Braided flexi connector, 15 mm x 350 mm female/female , tap and toilet hookups
- Cobra Zambezi single-lever basin mixer , a common mid-range tap
- Vaal Refine close-couple cistern , a popular SABS-approved cistern
Item-by-item price comparison
1. Copper pipe, 15 mm x 5.5 m, Class 0 SABS
| Retailer | Price | Notes |
|---|---|---|
| Chamberlain | R329.00 | On promo, was R415 |
| Build It (DTM) | R384.90 | Standard SABS |
| Mercury Build It | R389.99 | SABS |
| Build Africa Hardware | R430.10 | Class 460/0 |
| Cashbuild (equiv. 4 x 1.5 m) | ~R472 | Only sells 1.5 m and 2 m off-cuts , works out more per metre |
Winner: Chamberlain, with Build It a close second when Chamberlain is out of promo. Cashbuild is the worst place to buy copper by the full length because they cut it into 1.5 m and 2 m sections , convenient for a single repair, expensive for a re-pipe.
2. PVC waste pipe, 40 mm x 6 m
| Retailer | Price | Notes |
|---|---|---|
| Brights Hardware | From R42 (cut lengths) | Marley E-spec |
| Livestainable | R118.99 (was R128.99) | 6 m SANS |
| Cashbuild | ~R119 | Marley soil & vent E-spec |
| Builders Warehouse | listed but variable | Marley brand, often around R130-R160 in store |
Winner: Cashbuild for full 6 m lengths at trade price. Brights only beats them if you genuinely need a short cut piece.
3. PTFE (plumbers') tape
| Retailer | Price | Notes |
|---|---|---|
| Adendorff (MAC Afric) | R5.00 | 12 mm x 10 m, single roll |
| Leroy Merlin | R15.00 | 12 mm x 7 m |
| Cashbuild | R57.95 | Pack of 8 (R7.24 each) |
| Builders Warehouse | ~R12-R18 each | Single roll |
Winner: Adendorff by a country mile for single rolls, Cashbuild if you are buying in bulk for a workshop.
4. Braided flexi connector, 15 mm x 350 mm F/F
| Retailer | Price | Notes |
|---|---|---|
| Mercury Build It | R34.99 | Standard braided |
| Builders Warehouse (Churrasco) | ~R39 | Listed online |
| Gelmar | R59-R79 | Branded |
| Leroy Merlin | R45-R55 | Pro range |
Winner: Build It / Builders Warehouse are within rand of each other. Avoid the no-name R10 connectors at street markets , they are the single biggest cause of insurance-claimable burst-pipe damage in Gauteng flats.
5. Cobra Zambezi single-lever basin mixer (Lixil RSP)
The Lixil recommended retail price sits around R1,750-R1,950. In practice:
- Makro and Builders Warehouse: typically R1,499-R1,699 on promo
- Cashbuild: often unstocked , Cobra is a premium brand for them
- Brights Hardware: usually within R50 of Builders
- Leroy Merlin: matches Builders on most Lixil SKUs
Winner: Makro on promo, Builders Warehouse as the reliable everyday price. Always check the Makro app on a Sunday, Lixil specials run almost monthly.
6. Vaal Refine close-couple cistern
Lixil RSP is R3,669.75. Retail reality:
- Builders Warehouse: typically R2,799-R3,199
- Leroy Merlin: very competitive on Vaal, often R2,750
- Makro: best when bundled with the pan as a combo (around R3,800 for cistern + pan)
- Cashbuild: stocks mostly Lecico, not Vaal
Winner: Leroy Merlin for the cistern on its own, Makro if you need the full toilet suite.
The total basket , who is actually cheapest?
Adding up a realistic mixed trolley (1 x copper length, 1 x waste pipe, 5 rolls PTFE, 4 flexis, 1 basin mixer, 1 cistern):
| Retailer | Approx. total | Notes |
|---|---|---|
| Builders Warehouse | ~R4,950 | Wins on convenience, has everything in one trip, decent on every line |
| Cashbuild | ~R5,100 | Wins on commodity items (waste pipe, fittings), weak on branded ware |
| Leroy Merlin | ~R4,890 | Cheapest if you live near one (mostly Gauteng & WC) |
| Makro | ~R5,050 | Best when you can stack Lixil promos + Makro Money |
| Build It | ~R5,200 | Strong on copper and fittings, weaker on tap/cistern range |
| Brights Hardware | ~R5,150 | Excellent Cape Town option, great for cut PVC |
So , where should you actually go?
For a homeowner doing one repair, the honest answer is:
Drive to whichever big-box is closest (Builders or Leroy Merlin), and accept that you will overpay R30-R80 versus the absolute cheapest. The fuel and time to chase three stores is not worth it.
For a plumber, landlord, or anyone doing a full bathroom, the cheapest realistic plan is:
- Cashbuild for commodity stock: PVC waste, fittings, bulk PTFE, galvanised, cement
- Leroy Merlin or Makro for branded ware: Cobra, Vaal, Geberit (watch the monthly Lixil promos)
- Adendorff for tools, consumables and the R5 PTFE rolls
- Builders Warehouse as your back-up , they almost always have stock when the others do not
Avoid buying pressure-rated items (geyser fittings, copper, mixer cartridges) from informal stores. The R20 you save will cost you a R40,000 insurance claim the first time a no-SABS olive lets go on a hot line.
A note on the "cheap" online sellers
Takealot, Builders Online and a wave of dropship sites often look 10-20% cheaper than in-store, but:
- Delivery on a 5.5 m copper pipe usually adds R250-R450
- Returning a faulty Lixil tap by courier is a nightmare , in-store warranty swaps take 10 minutes
In-store wins for plumbing 9 times out of 10. Use online only for small, light, branded items (cartridges, aerators, shower roses) where the price gap is real and the courier cost is minimal.
Verdict
If we had to name one store as the cheapest reliable place to buy plumbing supplies in South Africa in 2026, it would be Cashbuild for commodity items + Leroy Merlin for branded ware, used together. For a one-stop trip, Builders Warehouse is still the best balance of price, range and stock availability nationwide.
And if a plumber on your job quotes you "Lixil retail" pricing on materials, send them this article , the trade price is almost always 20-35% below RSP, and a fair plumber will pass at least part of that saving on.
