MARNHOLD Journal · Shower planning guide
A shower system can look complete in a photograph while still needing parts or plumbing work you have not planned for. Choose the daily experience you want, then check what your water supply, enclosure and installation can support.
Know what a shower system includes
A typical combination may bring together an overhead head, hand shower, hose, rail and mixer. The contents vary: some sets include the valve or concealed body, while others supply only the visible fittings.
Read the component list for the exact model. A photograph showing several functions does not tell you whether they can operate together or whether extra plumbing parts are needed.
Exposed or concealed: plan around the work involved
An exposed system keeps its mixer and connecting parts visible on the wall. A concealed arrangement places some components behind the finished surface, leaving the controls and outlets visible.
For a replacement, compare existing pipe positions, connection centres and fixing points. For a renovation, plan concealed depth, waterproofing and future maintenance access with your installer before tiling. Neither arrangement is automatically a direct replacement for the other.
Check pressure, flow and hot-water capacity
Pressure and flow are different checks: pressure concerns the supply conditions, while flow describes the amount of water available over time. The chosen system must suit both the manufacturer’s requirements and your home’s supply.
A larger head is not a guarantee of a stronger shower. Ask your installer to check working pressure, available flow and hot-water capacity for the planned configuration, especially if multiple outlets may run together.
Do not use a generic pressure figure for every shower. Follow the requirements for the exact mixer, head and configuration you intend to install.
Choose controls and positions you can use comfortably
Check whether the mixer is manual or thermostatic; do not assume that buttons, a shelf-style body or a temperature display provide thermostatic control. Confirm any stated safety features in the product information.
Consider the tallest and shortest users, ceiling clearance, glass-door movement and access to the controls. Check whether the head position or handset holder is adjustable. The installer should confirm suitable positions and local installation requirements.
Your shower-system buying checklist
Confirm the full configuration before placing an order.
- Required water pressure, flow and hot-water supply checked.
- Exposed or concealed installation and existing connections confirmed.
- Valve, concealed body, hose and mounting parts checked against the contents list.
- Head, controls and hand shower positioned for the actual enclosure.
- Outlet switching, simultaneous use and stated safety features confirmed.

Your questions, answered
Does every shower set include the mixer valve?
No. Some sets include a mixer or concealed body and others do not. Check the exact contents list and any parts sold separately.
Is a bigger overhead shower always better?
No. The enclosure, user position, available flow and product requirements matter more than diameter alone. Choose a head that suits the complete installation.
