HammerHead Showers Dual Combo vs Delta In2ition: A Contractor's Review

Hey folks, Marcus here. When you're doing a bathroom renovation, picking the right shower head can feel a bit overwhelming. Today, we're putting two popular dual shower systems head-to-head: the HammerHead Showers Dual Shower Head Combo - 8" Rainfall and the Delta In2ition 2-in-1 Shower Head.

Both give you the flexibility of a fixed head and a handheld, but they take very different approaches to materials and performance. Let's dig into the details and see which one belongs in your bathroom.

Before we dive deep into the specific materials and contractor details, let's take a look at how these two systems stack up on paper.

Technical Specs, Flow Rates, and Materials

When evaluating shower fixtures, I always look at the materials first. Plastic threads crack; metal threads last.

The HammerHead Showers Dual Combo is built like a tank. It features solid metal construction, including a 3-way brass diverter and a commercial-grade metal finish. If durability is your primary concern, this is the way to go. The flow rate is a robust 2.5 GPM (gallons per minute), providing a heavy, satisfying downpour.

On the other hand, the Delta In2ition uses predominantly plastic components to keep the weight down and the price reasonable. It operates at a water-efficient 1.75 GPM. While it won't dump as much water on you as the HammerHead, it's WaterSense certified, which is great if you're looking to cut down on your utility bills.

No, some states like California and New York restrict shower flow rates to 1.8 GPM to conserve water. Always check your local plumbing codes before purchasing a high-flow shower head.

Because of its premium construction that ensures longevity and prevents frustrating leaks over time, there is a clear favorite for this category.

Water Pressure Intensity and Spray Patterns

Water pressure is often the deciding factor for my clients. The HammerHead delivers a high-pressure water flow that is incredibly consistent. However, it only offers a single water pressure setting for both the 8-inch rainfall head and the handheld unit. It does one thing, but it does it exceptionally well.

The Delta In2ition shines when it comes to versatility. It features 6 unique spray modes, including their ProClean high-pressure cleaning spray. This variety allows you to dial in the exact shower coverage and intensity you want, whether that's a wide spray for rinsing or a targeted massage.

The dock-in-dock design is also clever, allowing simultaneous dual shower head flow without looking bulky. Just keep in mind that splitting a 1.75 GPM flow between two heads will result in a noticeable pressure drop.

Thanks to the wide array of spray choices and the dock-in-dock flexibility, the choice for versatility is straightforward.

Installation Ease and Maintenance

Both of these systems are designed for DIY installation, meaning you won't necessarily need to call someone like me to get them running.

The HammerHead boasts an easy 10-minute installation. The solid metal threads mean you can tighten it down securely without fear of cracking the connection. For maintenance, metal finishes are durable but might require a bit more elbow grease to keep water spots at bay. The included 6-foot metal hose is fantastic for reach but can be a bit cumbersome in smaller shower stalls.

Do I need plumber's tape for a DIY installation? expand_more

Yes, it is highly recommended to use thread seal tape (Teflon tape) on the shower arm threads to prevent leaks, even if the new shower head comes with its own rubber washers.

The Delta model is incredibly user-friendly to maintain. It features Touch-Clean spray holes, which are basically little rubber nubs that let you wipe away calcium and lime build-up with a swipe of your finger. Installation is straightforward, though you need to be gentle when tightening the plastic fittings to avoid stripping them.

Both models offer unique benefits when it comes to getting them set up and keeping them clean over time, making this category too close to call.

If you want a buy-it-for-life fixture with heavy water flow and bulletproof construction, the HammerHead Showers Dual Combo is worth the higher price tag. It's an investment in solid brass and stainless steel.

However, if you're on a budget, want to conserve water, and love having multiple spray options, the Delta In2ition 2-in-1 is an excellent choice. It provides great versatility in an innovative package.
