How to Unlock the Sewers in Stardew Valley?

Stardew Valley features a ton of unique and exciting areas for its players to explore, all of which include various threats and potential rewards. The Sewers is at the top of the list for many Stardew Valley players, as it boasts various awesome items and in-game experiences – but, it can be somewhat tricky to access and unlock early on in the game.

The Sewers can be unlocked by donating 60 artifacts or minerals to the Museum, after which Gunther will hand the player a Rusty Key (The Sewer Key). The Sewers can be accessed from two locations after obtaining the key, namely at the south end of the Cindersap Forest and near the graveyard in town.

Although finding and unlocking the Sewers in Stardew Valley can feel complex and frustrating, it is pretty straightforward once you know what to look out for. Stick around to find out everything you need to know about the Sewers in Stardew Valley, as well as how to unlock it and make use of everything it has to offer.

The Sewers In Stardew Valley

The Sewers in Stardew Valley is a specific area that players will only be able to access after completing certain tasks in-game. It may seem odd to have such a secretive sewer area, but there is a reason why the Sewers area is locked at first.

Stardew Valley’s sewers hold some rather interesting and unique opportunities for Stardew Valley players. We’ve outlined all of the most significant benefits of unlocking the Sewers in Stardew Valley, with images thanks to Swipe Tips.

What’s Inside The Sewers?

Stardew Valley players will be able to take advantage of a few things once they enter the Sewers, making this area quite sought after. It may take some time, but the items and availabilities definitely make it worthwhile.


This area is home to Krobus, who sells players a ton of awesome and even rare items. One of the best things about this merchant is that he is open around the clock – even on festival days!

Below is a list of the items that can be purchased from Krobus’s shop, according to The Gamer:

Void Egg5,000g
Void Essence100g
Solar Essence80g
Sign of the Vessel350g
Monster Fireplace20,000g
Crystal Floor Recipe500g
Wicked Statue Recipe1,000g
Return Scepter2,000,000g

He sells a selection of items each day, with a special item being sold in rotation each weekday as well. Once you access the Sewers, keep an eye out for the day of the week in order to get exactly what you’re looking for.

Wednesday(Fish or Magnet)
Tiger Trout
ThursdayMixed Seeds30g
FridayIridium Sprinkler10,000g
SaturdayWide variety of cooked dishes50 – 500g
SundayBat Wing30g

Krobus is considered to be one of the best characters in the entire game. He is considered a monster at first, as he is technically a shadow person. But, after players get to know him a bit more, it’s clear that he’s actually quite a nice guy.

He may be shy, but he is the only friendly monster that players will encounter once they enter the Sewers area. In fact, he’s so loveable that single players can ask him to become their roommate (platonic, of course) by giving him a Void Ghost Pendant.

Mutant Bugs

The mutant bug lair inside the Stardew Valley Sewers area can be pretty useful for players seeking Bug Meat. Bug Meat can be used to craft bait, making this a pretty nice spot for gathering resources.

In addition, this is the only spot in the entire game where players can catch a unique and rare fish named Slimejack. Although, players will need to be careful as these bugs will attack.

But, gaining access to this area won’t be as simple as accessing the Sewer itself. Players will only be able to access the Mutant Bug area after they begin the Dark Talisman Quest.

Fishing Spot

While it may feel disgusting to fish in any sewer system, Stardew Valley’s sewers are home to an incredibly valuable fish species. Players can get their hands on one of the five legendary fish that are available in the game – it is the only place players can catch Mutant Carp.

Mutant Carp can be caught all year round and it does not have any special requirements for fishing, but it does have a difficulty of 80. According to IGN, every time players fish in the Sewers, players will have a 10% chance of getting a Mutant Carp on their line.

Other than special fish species, players can also fish for Carp, Green Algae, and White Algae. There is a chance you’ll end up with sewer trash, but it’s definitely worth a shot!

How To Unlock The Sewers In Stardew Valley

Now that we’ve covered the most irresistible benefits of accessing the Sewers in Stardew Valley, it’s time to get ready to unlock the area. Unlocking the Sewers in Stardew Valley is actually surprisingly easy – although, it will take some time and solid grinding.

All players will need to do to unlock the Sewers is obtain the Sewer Key, which is rewarded by Gunther at the Museum. Players will need to donate artifacts and minerals to the Museum in order to be given the Sewer Key.

The Museum can be found on the far edge of town, right under the Blacksmith area where players can find Clint. Players will need to find artifacts and minerals to donate through mining, cracking open geodes, and digging up artifact spots located on the ground in order to unlock the Sewers.

How Many Artifacts Do You Need for The Sewer Key?

The Sewer Key, also known as a Rusty Key, will be available to players from the Museum. But, players will need to donate at least 60 items, after which Gunther will hand over a Rusty Key.

A cutscene will play the next morning, where Gunther will thank the player for their efforts and explain that he does not know what the Rusty Key is for. But, this key is in fact the Sewer Key, and players will be able to use it to unlock the Sewers area.

Fastest Way To Unlock The Sewers

Players can typically get their hands on artifacts and minerals by mining at the Mines, which are situated in the northeast area of the map. Players may also come across geodes while mining, which can be taken to Clint the Blacksmith where he will crack open the geodes and potentially reveal another donatable item.

Additionally, players can use a hoe to dig up artifacts in specific spots. These spots are pretty easy to single out, as they are typically indicated by an odd pattern in the ground – it may look like a patch of land with squirming worms coming out of it.

Gunther will visit the player at their home and hand over the Rusty Key/ Sewer Key after this requirement is met. After this point, it’s time to head over to the Sewers.

Where Are The Sewers In Stardew Valley?

The Sewers can be found to the south of Pelican Town. But, the Sewers technically runs underground through a vast area in Stardew Valley, and it can only be accessed from two points. According to the Stardew Valley Wiki:

“The Sewers can be entered either through the sewer cover in the south of Pelican Town or through the grates in the south of Cindersap Forest.”

How Do You Get To The Sewers In Stardew Valley?

There are two entrances to the Sewers in Stardew Valley, and both of these entrances can be opened using the Sewer Key.

The first Sewer entrance is located at the southernmost area of the map south of Marnie’s Ranch – from the south end of the Cindersap Forest as seen below. This is the Sewer entrance that most Stardew Valley players are familiar with.

It’s located right next to 2 Willow Lane where Emily and Haley reside. Head south from Marnie’s Ranch until you reach the river’s end and see a wooden bridge to the right.

Follow the bridge across a small island until you reach the other side of the rover. From this point, players should simply continue south until they reach the Sewer gate – the Sewers will be accessible after going down the staircase.

The second Sewer entrance is situated near the graveyard in the center of town, to the left of the Mayor’s Mansion as seen below. Players will be able to see a little fenced-off area with a square cover over the Sewers, marking the entrance.

While the Sewers have two entrances and two exits, these are connected as one space within the Sewer system itself. This means that the entrances/ exits can be used interchangeably – they can even be used as a shortcut from the town to Cindersap Forest or vice versa.

Sewer Key Not Working

Although it is rare, it is possible for players to experience bugs when it comes to the Sewer Key – discussed on certain Reddit threads. These bugs were initially unheard of, even for Stardew Valley’s creators themselves, but the explanation is rather understandable.

It seems that players may encounter issues with the Sewer Key when they install multiple mods – there may very well be a possible conflict between the installed files, which causes the bug. While the bug does not necessarily prevent players from receiving the Sewer Key, it can cause problems when trying to use it.

According to players who have experienced this bug, a possible door entry bug can occur after you reach the bottom of the mines, complete Krobus’s event, and retrieve the key. The bug was resolved after numerous patches, so players don’t have much to worry about here – just make sure to double-check file compatibility when installing multiple Stardew Valley mods.

Sewer Key Issues In Multiplayer

Another possible problem with the Sewer Key can occur when playing Stardew Valley in multiplayer mode. It is possible for a friend to be unable to unlock the Sewers using the Sewer Key in separate progress.

In order to prevent this from happening, players will need to make sure that both themselves and their friends have unlocked the Sewers area using the Sewer Key before going into multiplayer. Make sure you have the latest patch and update of Stardew Valley as well to prevent other related issues.

What Is The Statue In The Sewers In Stardew Valley?

The statue within the Stardew Valley Sewers is referred to as the Statue of Uncertainty. It is not a massive milestone in the game, but it’s a really useful statue as many players may find a need for it at some point in the game.

Once players access and unlock the sewers in Stardew Valley, they will be able to use the Statue of Uncertainty to change their chosen profession. Players can change their professions in this way at a low cost of only 10,000g.

The changing professions phenomenon will only occur the following day, however. After awakening from slumber, players will be met with a pop-up screen that reads “Choose a profession”, after which they can choose as they’d like.

What Is The Animal By The Sewers In Stardew Valley?

The animal that can occasionally be seen lurking outside of the Sewers in Stardew Valley is known as Trash Bear. Unlike many other games, new content becomes available with in-game time – as the years and seasons go by, new additions may arise.

One such addition is Trash Bear, as he will not be visible at the very beginning. He only arises once players start the third year in-game, appearing on the first non-rainy day of year three.

Trash Bear opens up a whole new adventure for players, as he offers some quests for players to complete. But, don’t worry, there is no rush – Trash bear will remain in the same spot after spawning until his quests have been finished off, meaning players will still have a few more seasons to talk to him.

Managing to receive the Sewer Key and unlock the Sewers in Stardew Valley can feel pretty daunting at the beginning, but the best way to go about it is to seek artifacts while playing the game. There are a ton of awesome in-game activities that players can mix in with their search for artifacts and minerals – you’ll be surpassing 60 donations and entering the Sewers in next to no time!
