Shower Chair OEM Suppliers: Three Hidden Costs That Eat Your Margin
If you are looking for a shower chair OEM supplier, do the arithmetic first: why does the same shower chair cost you nearly 30% more ex-works than it costs someone else?
The problem is not materials or labour. The three largest blocks of contract manufacturing cost on a shower chair are hidden where you cannot see them — package volume, mold cost sharing, and turnaround on outsourced steps. Miss them during supplier evaluation and, once the contract is signed, your margin starts being eaten away piece by piece.
1. Package size: the overlooked cost sink
On the ex-works price of a shower chair, materials take the largest share, labour a smaller one, and packaging a share far bigger than most buyers expect.
Some factories ship a shower chair as a bulky item, with a carton 30% larger than the chair itself. The reason is simple: the chair leaves the line as one welded frame that cannot be broken down. Once the carton is large, international freight jumps a tier. Sell a shower chair at USD 37 and freight takes more than ten dollars of it. The books show a profit; after freight, it is gone.
An OEM supplier that genuinely understands cross-border trade thinks about packaging at the design stage. How many sections the frame splits into, how a folding structure stows, how units nest in a carton — none of this is decided at packing time; it is decided when the molds are cut. Whether a chair folds down inside the 45 cm standard size decides whether each unit earns or loses.
2. Mold cost: you think it is a one-time expense
Most buyers ask a shower chair OEM supplier one question — how much is the mold? — and then treat it as a one-time cost. That is wrong.
Where molds really swallow margin is not the line on the quotation, it is the modifications. You want a different handrail shape — mold change. You want the suction base switched from round feet to square — mold change. You want to add a non-slip pad — another mold change. Most factories outsource their tooling, so every change brings a fresh quotation and a fresh delay from the outside shop. The mold cost looks reasonable at the first sample; by the third revision the total has doubled.
To judge whether an OEM supplier is truly flexible, do not listen to claims that they can modify it. Find out who cuts the molds. When they are cut in-house, changing a handrail shape is a matter of adjusting one molding machine in the workshop. When they are cut elsewhere, every change means a phone call, a quotation and a wait. The cost difference between the two is not on the quotation sheet — it is in the sampling cycle.
3. Outsourced steps: rush it and you pay more
No single factory finishes a shower chair on its own — tubes are cut, plastic parts molded, surfaces powder coated, manuals printed, packaging assembled. Five steps. If four of them sit with outside vendors, the moment you push for delivery they will tell you that faster costs extra.
What matters is not how large the workshop is but how many critical steps stay in-house. Molding your own plastic parts decides whether you can test the market with 50 units. Printing manuals yourself decides whether you can revise a version without waiting three days. Running your own packaging line decides whether anyone is watching the final step.
Three questions to ask a shower chair OEM supplier: who decides package dimensions, and is it managed from the design stage? How long does a mold change take, and who does it? Of the critical steps — molding, powder coating, assembly — how many wait on someone outside the factory?
Once those three answers are in, you will know whether you are talking to a factory or a trading company.
