5 Secrets to Minpaku Renovation: He Who Conquers the Plumbing, Conquers the Minpaku

When starting a minpaku (vacation rental) business, “renovation costs” typically represent the second-largest expense after the property purchase price.

Within a limited budget, where should you spend money, and where should you cut back? Get this decision wrong, and despite investing significant funds, you could end up facing the worst-case scenario: no bookings and poor reviews.

Let’s start with the conclusion of this article.

When renovating a minpaku property, concentrating your budget priority on “wet areas” (bathroom, toilet, washbasin, kitchen) is the fastest route to achieving high occupancy and premium pricing.

“Shouldn’t I splurge on a luxurious living room sofa?” “I want to focus on the bedroom wallpaper.”

Some of you may be thinking this way. However, when you analyze guest psychology and review trends, it’s undeniably the wet areas that determine success or failure.

In this article, we’ll thoroughly explain why wet areas matter so much, and reveal the “5 secrets” to renovation that maximize impact within a limited budget.

Why Do “Wet Areas” Hold the Key to Minpaku Business Success?

Before diving into the specific secrets, let’s understand why wet areas are so critically important.

Guests may view old buildings or furniture positively, seeing them as having “retro charm” or “character.” However, when it comes to old or dirty wet areas, they feel nothing but visceral disgust (i.e., they perceive it as unhygienic).

Many low-rated reviews on OTAs (booking platforms) relate to wet areas—complaints like “the bathroom smelled moldy,” “the toilet was so old I didn’t want to use it,” or “the kitchen sink was dirty.”

Conversely, even in an older property, if the wet areas are sparkling clean with modern fixtures, guests will perceive the property as “clean and comfortable” and give it high ratings. Renovating wet areas isn’t merely repair work—it’s an investment in purchasing the property’s “trustworthiness.”

Secret 1: [Bathroom] Cleanliness and “Plus-Alpha” Experience Value

The bathroom is the most important place for washing away the fatigue of travel. This is an area where you absolutely cannot compromise.

Separate 3-in-1 Unit Baths Whenever Possible

Especially when targeting domestic guests or those from other parts of Asia, the “3-in-1 unit bath” (where the toilet and bathtub share one space) tends to be avoided. If space and budget allow, consider converting to a **separate bath and toilet** layout. If structural constraints make this difficult, upgrading the shower curtain to something more luxurious and installing a large mirror are essential tricks to reduce the feeling of cramped space.

Projecting Cleanliness and Functionality

• Thermostatic Faucets: Two-handle faucets that make water temperature adjustment difficult cause guest stress. Replacing them with thermostatic mixing valves that allow easy temperature control is essential.
• Ensuring Water Pressure: Weak shower water pressure significantly lowers guest satisfaction. Consider replacing showerheads with low-pressure-optimized models and checking your water heater’s capacity.
• Visual Cleanliness: Mold in tile grout and mineral buildup on mirrors are simply unacceptable. If cleaning alone can’t remove these issues, panel renovation methods can restore walls to like-new condition while keeping costs down, giving the space a fresh, brand-new shine.

Secret 2: [Toilet] The “Washlet” Is a Universal Must-Have Feature

The toilet is an area where Japanese accommodations are expected to deliver world-class quality.

Heated Bidet Seats Are a Must

Nowadays, even for inbound guests, a heated bidet seat (washlet) is a “taken-for-granted” fixture. Its absence alone can knock your property out of consideration during the booking process. It doesn’t need to be the latest high-tech model, but you should always install one that’s clean and works properly.

Enhancing the Space

Because the toilet is a small space, even minor touches can dramatically transform its impression.

• Accent Wallpaper: Change just one wall to a stylish, design-forward wallpaper.
• Toilet Paper Holder: Swap out a cheap-looking plastic holder for one made of iron or wood. This kind of low-budget renovation alone can convey the impression of “a property with careful attention to detail.”

Secret 3: [Kitchen] Elevating the “Live-Like-a-Local” Satisfaction Level

The kitchen—your biggest point of differentiation from hotels—is key to securing long-term stay guests.

Balancing Appearance and Practicality

While few guests will cook elaborate meals, there’s strong demand for things like “making a simple breakfast” or “cutting up fruit they’ve bought.”

• Clean Sink: Thoroughly polish away any dullness or rust on stainless steel surfaces, or replace the sink entirely.
• Induction Cooktops: We recommend switching to IH induction cooktops, which reduce fire risk and are easier to clean.
• Photogenic Appliances: For refrigerators, microwaves, and electric kettles, prioritize design as well as function. Simply featuring popular brands like Balmuda or De’Longhi can dramatically boost the appeal of your listing photos.

Secret 4: [Cost Management] Concentrate Investment on Areas That Directly Affect Appearance

For renovations outside of wet areas, be relentlessly conscious of cost-effectiveness.

Shaping Impressions with Wallpaper and Flooring

Since walls and floors occupy a large portion of the visual field, renovating them creates the strongest impression that “the room has changed.”

• Accent Wallpaper: If you don’t have the budget to replace wallpaper throughout, simply applying colored or patterned wallpaper to a single eye-catching wall—like the headboard side of the bed or behind the TV—can make the whole room look stylish.
• Floor Tiles: Floor tiles that can be installed directly over old flooring or carpet are easy to apply, highly durable, and a staple choice in minpaku renovations.

Upgrading with Furniture and Lighting

Rather than overspending on interior construction work, allocate budget to items that transform the space simply by being placed there.

• Lighting: Fluorescent ceiling lights give off a “lived-in” feel. Combine downlights, pendant lights, and indirect lighting with warm-toned light to create a “sense of escape from the everyday.”
• Furniture: Invest in sofas and bed mattresses that guests spend extended time in contact with, while keeping costs down on tables and shelves that wear out quickly by sourcing them from places like IKEA or Nitori. This kind of strategic prioritization is essential.

Secret 5: [Maintainability] Choose Materials That Are Easy to Clean and Durable

Since minpaku properties are used by an unspecified number of different people, they experience far more wear and get dirty far more easily than typical residential homes. You should avoid materials that are “stylish but easily stained” or “delicate and fragile.”

Choosing Materials That Improve Cleaning Efficiency

• Flooring: Choose commercial-grade cushion flooring or floor tiles that resist scratches and can be wiped down with water. While solid wood flooring is beautiful, it’s difficult to maintain.
• Wallpaper: Select functional wallpaper that’s easy to wipe clean, or wallpaper with a surface treatment that makes scratches less noticeable.
• Rugs and Carpets: Assuming spills will happen, choose washable options or colors/patterns that don’t show stains easily.

Creating an environment where cleaning staff can achieve a spotless result in a short amount of time directly translates into reduced operating costs (cleaning expenses).

Conclusion: Renovation Is a “Love Letter to Your Guests”

The purpose of minpaku renovation isn’t simply to make a room look nice.

It’s about giving tangible form to a host’s desire to thoroughly care for the areas guests care about most—the wet areas—and to provide a comfortable stay.

What do you prioritize and what do you let go of within a limited budget? That strategic judgment is what boosts guest satisfaction and, as a result, delivers substantial profit to your minpaku business.

“He who conquers the wet areas conquers the minpaku.” Keep this phrase in mind as you build an effective renovation plan.
