Shower comparison and buying guides

The core difference comes down to showerhead size and how water is delivered. A standard showerhead is typically 2–4 inches and shoots water in a focused, directional stream — efficient and quick. A rain showerhead is much larger, usually 6–12 inches across, and releases water in a wide, soft cascade that falls straight down like actual rainfall. The sensation is completely different — much more immersive and full-body rather than targeted. Rain showers are generally better for relaxation, while standard showers offer more concentrated pressure for a faster rinse. Most people who upgrade to a rainfall shower keep a handheld spray in the mix too, so they don't lose the focused-rinsing option. A system like the Polaris series gives you both in one kit.

You don't have to choose — and honestly, you shouldn't. Rain showers and handheld showers serve different purposes, and having both is the most practical setup for most households. A rain shower gives you that immersive, full-body experience that's hard to replicate with anything else. A handheld shower gives you the control and flexibility you need for rinsing hair, spot cleaning, bathing kids or pets, or cleaning the shower walls. Fennocasa's Polaris series is built around exactly this logic — every system comes with both a rainfall showerhead and a handheld wand in one package, connected via a simple diverter. You switch between them with a turn of a knob. Once you've used both together, going back to a single showerhead feels like a real step down.

When shopping for a rain shower system, these are the five things that matter most: showerhead size (bigger gives better coverage — 8–10 inches is ideal for most showers), water pressure compatibility (especially if your home has lower pressure), material quality (stainless steel and brass outperform plastic significantly), included components (some brands sell the head and handheld separately), and warranty coverage. A system backed by a lifetime warranty — like the Fennocasa Polaris line — signals genuine confidence in the product's durability. Also check whether the system is retrofit-compatible, meaning it works with your existing plumbing without a remodel. For most buyers, a retrofit rain shower installation is the right starting point.

Rain shower maintenance is straightforward and doesn't require any special tools or products. The biggest issue over time is mineral buildup from hard water, which can clog the nozzles and reduce water pressure. Every 4–6 weeks, soak the showerhead in a bag of white vinegar for 30–60 minutes — this dissolves limescale naturally without damaging the finish. For chrome or brushed nickel finishes, a quick wipe with a soft cloth after each use prevents water spots from hardening. Avoid abrasive scrubbers or harsh chemical cleaners, which can scratch the surface. The handheld hose connections are also worth checking every few months. Fennocasa has a detailed cleaning guide on their website specifically for their Polaris systems.

For most US homes, installing a rain shower system is a straightforward DIY project — no plumber needed. A retrofit system like the Polaris 3 connects directly to your existing shower arm using standard ½-inch IPS threading, the same connection used by virtually every US showerhead. The process takes 20–30 minutes and requires only a wrench and some plumber's tape. Fennocasa includes a printed step-by-step rain shower installation guide in the box and has video tutorials on their website. The only time a plumber makes sense is if your existing shower arm is damaged, corroded, or non-standard. For everything else, this is genuinely a beginner-friendly installation that most homeowners and renters can handle comfortably on their own.
