GROHE

GROHE is a German sanitary fittings brand with a history dating to 1911, when Friedrich Grohe acquired a small plumbing workshop in Hemer, Westphalia. Over the following decades the company expanded into a full-range manufacturer of kitchen and bathroom fixtures, and since 2014 it has operated as part of the LIXIL Group. GROHE's product portfolio spans kitchen faucets, bathroom faucets, shower systems, thermostatic and pressure-balance mixing valves, concealed cisterns, and the cartridges, handles, aerators, and connection fittings that support those assemblies. The brand is widely specified in residential, hospitality, and commercial construction because its components are designed to standardized connection interfaces and are supported by published spare-part documentation, which simplifies long-term maintenance and replacement planning.

About GROHE

GROHE is a German sanitary fittings brand with a history dating to 1911, when Friedrich Grohe acquired a small plumbing workshop in Hemer, Westphalia. Over the following decades the company expanded into a full-range manufacturer of kitchen and bathroom fixtures, and since 2014 it has operated as part of the LIXIL Group. GROHE's product portfolio spans kitchen faucets, bathroom faucets, shower systems, thermostatic and pressure-balance mixing valves, concealed cisterns, and the cartridges, handles, aerators, and connection fittings that support those assemblies. The brand is widely specified in residential, hospitality, and commercial construction because its components are designed to standardized connection interfaces and are supported by published spare-part documentation, which simplifies long-term maintenance and replacement planning.

3G Electric supplies GROHE plumbing parts as individual service components rather than complete fixture sets. The current catalog includes 96 SKUs, with recent additions concentrated in three areas: handheld showerhead assemblies, wall elbows for shower outlets, and temperature and flow control components for bathtubs and showers. Representative items include the Euphoria Cube handheld showerhead (MPN 27891000), a chrome-finished unit with a 2.5 gpm flow rate and 4 1/2 in head width, supplied with hose, mounting bracket, and slide bar. Wall unions are offered in chrome and brushed nickel with 1/2 in NPT connections, including MPNs 28459EN0 and related outlet elbows. On the control side, 3G Electric stocks the Universal-series thermostatic control unit (MPN 47853000), the Universal pressure-balance control unit kit (MPN 47864000), and Universal water-saving aerator kits (MPNs 48187000 and 48188000).

For technical buyers, the relevant characteristics of these parts are their connection standards, finish options, and series compatibility. The wall elbows use 1/2 in NPT threads, which is a common interface in North American and export plumbing systems. Finishes include polished chrome and brushed nickel, allowing replacement parts to match existing fixture trim. The control units and aerator kits are designated for the GROHE Universal series, so compatibility should be confirmed against the existing valve body or faucet model before ordering. Flow rates on the showerhead assemblies are stated in gpm, which matters where fixture flow is regulated by local code or by a facility's water-management program.

3G Electric's role is to make these service parts available as discrete line items with manufacturer part numbers, specifications, and logistics support. The catalog is structured so that a maintenance planner or procurement specialist can identify a replacement cartridge, wall union, or control unit by MPN and cross-reference it against the installed fixture. Because the parts are supplied individually, buyers can address a failed component without replacing an entire shower or faucet assembly. 3G Electric ships globally and can quote on single units or larger maintenance quantities; inquiries should include the MPN and, where relevant, the model of the existing fixture to confirm series compatibility.

Common Applications

  • Hospitality and multi-unit residential — GROHE Euphoria Cube handheld showerhead (MPN 27891000) for standardized guest bathroom replacement

  • Bathtub and shower valve replacement — GROHE Universal thermostatic control unit (MPN 47853000) for temperature regulation
  • Facility water management — GROHE pressure-balance control unit kit (MPN 47864000) to limit temperature swings from supply pressure changes
  • Plumbing parts procurement — GROHE service components identified by MPN for maintenance stock and single-unit replacement orders

Frequently asked questions

Common questions about GROHE from 3G Electric.

What is the difference between the GROHE thermostatic control unit (MPN 47853000) and the pressure-balance control unit kit (MPN 47864000)?

Both are Universal-series temperature and flow control components for bathtubs and showers, but they use different mixing principles. The thermostatic control unit (47853000) regulates outlet temperature by responding to changes in hot and cold supply temperatures, holding a set point as supply conditions vary. The pressure-balance control unit kit (47864000) responds primarily to pressure fluctuations between the hot and cold supplies, adjusting flow to limit temperature swings. Selection depends on the valve body already installed and the level of temperature stability required. Confirm the existing valve model before ordering, since the two types are not interchangeable within the same rough-in.

What connection type do GROHE wall elbows for handheld showerheads use?

The GROHE wall unions and shower outlet elbows in the 3G Electric catalog use 1/2 in NPT connections. This applies to the chrome-finished outlet elbow (MPN 28459EN0) and the brushed nickel wall union variants. The 1/2 in NPT thread is a standard tapered pipe thread, so the elbow threads onto a matching wall supply outlet and provides the transition to the shower hose. Finish options include polished chrome and brushed nickel. When replacing an existing wall elbow, verify the thread type on the wall stub-out, as some markets use parallel thread standards rather than NPT.

What is included with the GROHE Euphoria Cube handheld showerhead (MPN 27891000)?

The Euphoria Cube handheld showerhead assembly is supplied with the showerhead, hose, mounting bracket, and slide bar. The showerhead is chrome-finished, has a width of 4 1/2 in, and is rated at 2.5 gpm. The slide bar allows the head height to be adjusted along the bar, and the mounting bracket secures the assembly to the wall. Because the kit includes the hose and wall-mounting hardware, it can be used to replace a complete handheld shower set rather than just the head. Confirm the wall supply connection matches the included hose fitting before installation.

What does the GROHE Universal water-saving kit include, and which fixtures is it compatible with?

The GROHE Universal water-saving kits (MPNs 48187000 and 48188000) are low-solution kits for temperature and flow control in bathroom and kitchen faucets. Each kit includes an aerator. They are designated as compatible with the GROHE Universal series of faucets. The aerator fits into the faucet outlet and introduces air into the water stream, which maintains a consistent flow pattern at a reduced volumetric flow rate. These kits are typically used when replacing a worn aerator or when adjusting a faucet to meet a lower flow requirement. Verify the faucet model against the Universal series listing before ordering.

How do I identify the correct GROHE replacement part for an existing fixture?

Start with the manufacturer part number (MPN) if it is known, since 3G Electric lists GROHE parts by MPN in the catalog. If the MPN is not available, identify the fixture series and model from the installation documentation or from markings on the valve body or faucet. Many of the control components in the 3G Electric catalog are designated for the GROHE Universal series, so the series name is a useful filter. For wall elbows and shower outlets, confirm the connection size and thread type, which for the listed items is 1/2 in NPT. Providing the existing fixture model with an inquiry helps confirm compatibility before shipment.

Are GROHE shower and bath control parts available in different finishes?

Yes. The wall elbows and shower outlet components in the 3G Electric catalog are available in polished chrome and brushed nickel. For example, the chrome-finished shower outlet elbow (MPN 28459EN0) and brushed nickel wall union variants are both listed. Finish selection is typically made to match the existing trim on the shower or bath installation. The control units and water-saving kits are internal or outlet components, so finish is not a primary selection factor for those items. When ordering, specify the finish in addition to the MPN to avoid receiving a mismatched trim piece.
